############################################################################# # # Very limited CMake support for building some parts of XZ Utils # # For now, this is indented to be useful to build static or shared liblzma # 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 large file support on those 32-bit platforms that need it # - No replacement getopt_long(), libc must have it # - No sandboxing support # - No translations # - No xz symlinks are installed # # Other missing things: # - No xzgrep or other scripts or their symlinks # - No tests (no test failures either!) # # NOTE: Even if the code compiles without warnings, the end result may be # different than via ./configure. Specifically, the list of #defines # may be different (if so, probably this CMakeLists.txt got them wrong). # # 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) # ############################################################################# # # Author: Lasse Collin # # This file has been put into the public domain. # You can do whatever you want with this file. # ############################################################################# cmake_minimum_required(VERSION 3.13...3.16 FATAL_ERROR) include(CheckSymbolExists) include(CheckStructHasMember) include(cmake/tuklib_integer.cmake) include(cmake/tuklib_cpucores.cmake) include(cmake/tuklib_physmem.cmake) include(cmake/tuklib_progname.cmake) include(cmake/tuklib_mbstr.cmake) # Get the package version from version.h into XZ_VERSION variable. file(READ src/liblzma/api/lzma/version.h XZ_VERSION) string(REGEX REPLACE "^.*\n\ #define LZMA_VERSION_MAJOR ([0-9]+)\n\ #define LZMA_VERSION_MINOR ([0-9]+)\n\ #define LZMA_VERSION_PATCH ([0-9]+)\n\ .*$" "\\1.\\2.\\3" XZ_VERSION "${XZ_VERSION}") # Among other things, this gives us variables xz_VERSION and xz_VERSION_MAJOR. project(xz VERSION "${XZ_VERSION}" LANGUAGES C) # On Apple OSes, don't build executables as bundles: set(CMAKE_MACOSX_BUNDLE OFF) # Definitions common to all targets: add_compile_definitions( # Package info: PACKAGE_NAME="XZ Utils" PACKAGE_BUGREPORT="lasse.collin@tukaani.org" PACKAGE_URL="https://tukaani.org/xz/" # Features: HAVE_CHECK_CRC32 HAVE_CHECK_CRC64 HAVE_CHECK_SHA256 HAVE_DECODERS HAVE_DECODER_ARM HAVE_DECODER_ARMTHUMB HAVE_DECODER_DELTA HAVE_DECODER_IA64 HAVE_DECODER_LZMA1 HAVE_DECODER_LZMA2 HAVE_DECODER_POWERPC HAVE_DECODER_SPARC HAVE_DECODER_X86 HAVE_ENCODERS HAVE_ENCODER_ARM HAVE_ENCODER_ARMTHUMB HAVE_ENCODER_DELTA HAVE_ENCODER_IA64 HAVE_ENCODER_LZMA1 HAVE_ENCODER_LZMA2 HAVE_ENCODER_POWERPC HAVE_ENCODER_SPARC HAVE_ENCODER_X86 HAVE_MF_BT2 HAVE_MF_BT3 HAVE_MF_BT4 HAVE_MF_HC3 HAVE_MF_HC4 # Standard headers and types are available: HAVE_STDBOOL_H HAVE__BOOL HAVE_STDINT_H HAVE_INTTYPES_H # Disable assert() checks when no build type has been specified.
