Build: Add very limited experimental CMake support. This does *NOT* replace the Autotools-based build system in the foreseeable future. See the comment in the beginning of CMakeLists.txt. So far this has been tested only on GNU/Linux but I commit it anyway to make it easier for others to test. Since I haven't played much with CMake before, it's likely that there are things that have been done in a silly or wrong way and need to be fixed.

# on Windows with MSVC (to avoid the need to maintain Visual Studio project
# files). Building liblzma on a few other platforms should work too but it
# is somewhat experimental and not as portable as using ./configure.
#
# On some platforms this builds also xz and xzdec, but these are
# highly experimental and meant for testing only:
# - No replacement getopt_long(), libc must have it
# - No sandboxing support
# - No translations
#
# Other missing things:
# - No xzgrep or other scripts or their symlinks
CMake: Add liblzma tests. Thanks to Jia Tan for the patch.

# This file provides the following installation components (if you only
# need liblzma, install only its components!):
# - liblzma_Runtime
# - liblzma_Development
# - xz (on some platforms only)
# - xzdec (on some platforms only)
#
# To find the target liblzma::liblzma from other packages, use the CONFIG
# option with find_package() to avoid a conflict with the FindLibLZMA module
# with case-insensitive file systems. For example, to require liblzma 5.2.5
# or a newer compatible version:
#
# find_package(liblzma 5.2.5 REQUIRED CONFIG)
# target_link_libraries(my_application liblzma::liblzma)

CMake: Bump maximum policy version to 3.29

liblzma: Use __attribute__((__constructor__)) if available. This uses it for CRC table initializations when using --disable-small. It avoids mythread_once() overhead. It also means that then --disable-small --disable-threads is thread-safe if this attribute is supported.

liblzma: Add fast CRC64 for 32/64-bit x86 using SSSE3 + SSE4.1 + CLMUL. It also works on E2K as it supports these intrinsics. On x86-64 runtime detection is used so the code keeps working on older processors too. A CLMUL-only build can be done by using -msse4.1 -mpclmul in CFLAGS and this will reduce the library size since the generic implementation and its 8 KiB lookup table will be omitted. On 32-bit x86 this isn't used by default for now because by default on 32-bit x86 the separate assembly file crc64_x86.S is used. If --disable-assembler is used then this new CLMUL code is used the same way as on 64-bit x86. However, a CLMUL-only build (-msse4.1 -mpclmul) won't omit the 8 KiB lookup table on 32-bit x86 due to a currently-missing check for disabled assembler usage. The configure.ac check should be such that the code won't be built if something in the toolchain doesn't support it but --disable-clmul-crc option can be used to unconditionally disable this feature. CLMUL speeds up decompression of files that have compressed very well (assuming CRC64 is used as a check type). It is know that the CLMUL code is significantly slower than the generic code for tiny inputs (especially 1-8 bytes but up to 16 bytes). If that is a real-world problem then there is already a commented-out variant that uses the generic version for small inputs. Thanks to Ilya Kurdyukov for the original patch which was derived from a white paper from Intel [1] (published in 2009) and public domain code from [2] (released in 2016).

# windres from GNU binutils can be tricky with command line arguments
# that contain spaces or other funny characters. Unfortunately we need
# a space in PACKAGE_NAME. Using \x20 to encode the US-ASCII space seems
# to work in both cmd.exe and /bin/sh.
#
# However, even \x20 isn't enough in all situations, resulting in
# "syntax error" from windres. Using --use-temp-file prevents windres
# from using popen() and this seems to fix the problem.

CMake: Fix Windows build with Clang/LLVM 17. llvm-windres 17.0.0 has more accurate emulation of GNU windres, so the hack for GNU windres must now be used with llvm-windres too. LLVM 16.0.6 has the old behavior and there likely won't be more 16.x releases. So we can simply check for >= 17.0.0. The workaround must not be used with Clang that is acting in MSVC mode. This checks for the known environments that need the workaround instead of using "NOT MSVC". See also: https://github.com/llvm/llvm-project/commit/2bcc0fdc58a220cb9921b47ec8a32c85f2511a47

CMake: Don't shadow the cache entry ENABLE_THREADS with a normal variable.

Build: Add very limited experimental CMake support. This does *NOT* replace the Autotools-based build system in the foreseeable future. See the comment in the beginning of CMakeLists.txt. So far this has been tested only on GNU/Linux but I commit it anyway to make it easier for others to test. Since I haven't played much with CMake before, it's likely that there are things that have been done in a silly or wrong way and need to be fixed.

liblzma: Add fast CRC64 for 32/64-bit x86 using SSSE3 + SSE4.1 + CLMUL. It also works on E2K as it supports these intrinsics. On x86-64 runtime detection is used so the code keeps working on older processors too. A CLMUL-only build can be done by using -msse4.1 -mpclmul in CFLAGS and this will reduce the library size since the generic implementation and its 8 KiB lookup table will be omitted. On 32-bit x86 this isn't used by default for now because by default on 32-bit x86 the separate assembly file crc64_x86.S is used. If --disable-assembler is used then this new CLMUL code is used the same way as on 64-bit x86. However, a CLMUL-only build (-msse4.1 -mpclmul) won't omit the 8 KiB lookup table on 32-bit x86 due to a currently-missing check for disabled assembler usage. The configure.ac check should be such that the code won't be built if something in the toolchain doesn't support it but --disable-clmul-crc option can be used to unconditionally disable this feature. CLMUL speeds up decompression of files that have compressed very well (assuming CRC64 is used as a check type). It is know that the CLMUL code is significantly slower than the generic code for tiny inputs (especially 1-8 bytes but up to 16 bytes). If that is a real-world problem then there is already a commented-out variant that uses the generic version for small inputs.

liblzma: Add fast CRC64 for 32/64-bit x86 using SSSE3 + SSE4.1 + CLMUL. It also works on E2K as it supports these intrinsics. On x86-64 runtime detection is used so the code keeps working on older processors too. A CLMUL-only build can be done by using -msse4.1 -mpclmul in CFLAGS and this will reduce the library size since the generic implementation and its 8 KiB lookup table will be omitted.

Build: Don't put GNU/Linux-specific symbol versions into static liblzma. It not only makes no sense to put symbol versions into a static library but it can also cause breakage. By default Libtool #defines PIC if building a shared library and doesn't define it for static libraries. This is documented in the Libtool manual. It can be overriden using --with-pic or --without-pic. configure.ac detects if --with-pic or --without-pic is used and then gives an error if neither --disable-shared nor --disable-static was used at the same time. Thus, in normal situations it works to build both shared and static library at the same time on GNU/Linux, only --with-pic or --without-pic requires that only one type of library is built.

CMake: Try to improve compatibility with the FindLibLZMA module. The naming conflict with FindLibLZMA module gets worse. Not avoiding it in the first place was stupid. Normally find_package(LibLZMA) will use the module and find_package(liblzma 5.2.5 REQUIRED CONFIG) will use the config file even with a case insensitive file system. However, if CMAKE_FIND_PACKAGE_PREFER_CONFIG is TRUE and the file system is case insensitive, find_package(LibLZMA) will find our liblzma config file instead of using FindLibLZMA module. One big problem with this is that FindLibLZMA uses LibLZMA::LibLZMA and we use liblzma::liblzma as the target name. With target names CMake happens to be case sensitive. To workaround this, this commit adds add_library(LibLZMA::LibLZMA ALIAS liblzma::liblzma) to the config file. Then both spellings work. To make the behavior consistent between case sensitive and insensitive file systems, the config and related files are renamed from liblzmaConfig.cmake to liblzma-config.cmake style. With this style CMake looks for lowercase version of the package name so find_package(LiBLzmA 5.2.5 REQUIRED CONFIG) will work to find our config file. There are other differences between our config file and FindLibLZMA so it's still possible that things break for reasons other than the spelling of the target name. Hopefully those situations aren't too common. When the config file is available, it should always give as good or better results as FindLibLZMA so this commit doesn't affect the recommendation to use find_package(liblzma 5.2.5 REQUIRED CONFIG) which explicitly avoids FindLibLZMA.

Build: Fix bugs in the CMake files. Seems that the phrase "add more quotes" from sh/bash scripting applies to CMake as well. E.g. passing an unquoted list ${FOO} to a function that expects one argument results in only the first element of the list being passed as an argument and the rest get ignored. Adding quotes helps ("${FOO}"). list(INSERT ...) is weird. Inserting an empty string to an empty variable results in empty list, but inserting it to a non-empty variable does insert an empty element to the list. Since INSERT requires at least one element, "${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt. It might result in an empty element in the list. It seems to not matter as empty elements consistently get ignored in that variable. In fact, calling cmake_check_push_state() and cmake_check_pop_state() will strip the empty elements from CMAKE_REQUIRED_LIBRARIES! In addition to quoting fixes, this fixes checks for the cache variables in tuklib_cpucores.cmake and tuklib_physmem.cmake. Thanks to Martin Matuška for testing and reporting the problems. These fixes aren't tested yet but hopefully they soon will be.

CMake: Try to improve compatibility with the FindLibLZMA module. The naming conflict with FindLibLZMA module gets worse. Not avoiding it in the first place was stupid. Normally find_package(LibLZMA) will use the module and find_package(liblzma 5.2.5 REQUIRED CONFIG) will use the config file even with a case insensitive file system. However, if CMAKE_FIND_PACKAGE_PREFER_CONFIG is TRUE and the file system is case insensitive, find_package(LibLZMA) will find our liblzma config file instead of using FindLibLZMA module. One big problem with this is that FindLibLZMA uses LibLZMA::LibLZMA and we use liblzma::liblzma as the target name. With target names CMake happens to be case sensitive. To workaround this, this commit adds add_library(LibLZMA::LibLZMA ALIAS liblzma::liblzma) to the config file. Then both spellings work. To make the behavior consistent between case sensitive and insensitive file systems, the config and related files are renamed from liblzmaConfig.cmake to liblzma-config.cmake style. With this style CMake looks for lowercase version of the package name so find_package(LiBLzmA 5.2.5 REQUIRED CONFIG) will work to find our config file. There are other differences between our config file and FindLibLZMA so it's still possible that things break for reasons other than the spelling of the target name. Hopefully those situations aren't too common. When the config file is available, it should always give as good or better results as FindLibLZMA so this commit doesn't affect the recommendation to use find_package(liblzma 5.2.5 REQUIRED CONFIG) which explicitly avoids FindLibLZMA.

Build: Fix bugs in the CMake files. Seems that the phrase "add more quotes" from sh/bash scripting applies to CMake as well. E.g. passing an unquoted list ${FOO} to a function that expects one argument results in only the first element of the list being passed as an argument and the rest get ignored. Adding quotes helps ("${FOO}"). list(INSERT ...) is weird. Inserting an empty string to an empty variable results in empty list, but inserting it to a non-empty variable does insert an empty element to the list. Since INSERT requires at least one element, "${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt. It might result in an empty element in the list. It seems to not matter as empty elements consistently get ignored in that variable. In fact, calling cmake_check_push_state() and cmake_check_pop_state() will strip the empty elements from CMAKE_REQUIRED_LIBRARIES! In addition to quoting fixes, this fixes checks for the cache variables in tuklib_cpucores.cmake and tuklib_physmem.cmake. Thanks to Martin Matuška for testing and reporting the problems. These fixes aren't tested yet but hopefully they soon will be.

Build: Add very limited experimental CMake support. This does *NOT* replace the Autotools-based build system in the foreseeable future. See the comment in the beginning of CMakeLists.txt. So far this has been tested only on GNU/Linux but I commit it anyway to make it easier for others to test. Since I haven't played much with CMake before, it's likely that there are things that have been done in a silly or wrong way and need to be fixed.
