#
|
|
# Very limited CMake support for building some parts of XZ Utils
|
|
#
|
|
# For now, this is intended 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 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. 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)
