############################################################################# # # Very limited CMake support for building some parts of XZ Utils # # Building static liblzma with MSVC should work. Building shared liblzma.dll # with MSVC may or may not work (building liblzma_w32res.rc might be broken). # 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 # - 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.
