Just stumbled upon that problem. I have files like *.darwin.cpp And get_filename_component returns .darwin.cpp for the extension which is wrong! The extension is .cpp.
Let s take the example of toto.tar.gz. It s a gz file, not tar.gz file. To see why it s wrong we can think of file association, which is most cases would associate .gz and not .tar.gz Right now I use that regex "(\.[^\.]*)$" to get the right extension. But I really think it should be corrected.

I was expecting .gz and with successive calls I would get .tar Is there a mechanism in CMake for getting the trailing extension? -- Brian J. Davis
