No, the error is to use -llibfoo, the linker then searches for a file
called liblibfoo.so which does not not exist. But as I said, if you pass
absolute paths to CMake it usually uses them (I'm not sure right now
about that when the directory is a system-link-directory)

My guess would've been for the setting of the shared-lib prefix, maybe
thats whats causing the older CMake version to generate a -llibfoo
argument for the linker.
