Poor cmake installation support for windows.

[acidtonic]

Windows is all busted right now.

Builds the file inside the gen folder, the install target fails because it wants to find it in fmem/fmem.h.

I moved that. Now install fails trying to find fmem/fmem-export.h.

I think I'm just going to snag the files into my project with a sane build system. Just letting you know.
