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 +# +# Other missing things: +# - No xzgrep or other scripts or their symlinks +# - No xz tests (liblzma tests only) +# +# 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.
