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).
