+#
+# 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 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. 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)
