Jia Tan 5d351c69c1 Build: Adjust CMake version search regex. 
Now, the LZMA_VERSION_MAJOR, LZMA_VERSION_MINOR, and LZMA_VERSION_PATCH
macros do not need to be on consecutive lines in version.h. They can be
separated by more whitespace, comments, or even other content, as long
as they appear in the proper order (major, minor, patch).

#
# 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
#
# 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)
