[CMake] /path/to/libpng.so automatic conversion to -lpng ?

[Andreas Naumann]

Dear Rene,

cmake instrospects your compiler and asks for system directories. Only 
these system directories will be removed and the corresponding libraries 
will be linked by -l<...>. So, you should check your compiler and the 
environment. I had several problems years ago with the environment 
variable LIBRARY_PATH, which leads to such a behavior.

Regards,
Andreas

Instead, I am getting a linker command line that has `-lpng -lz`, which fails for me because the `/path/to` in question isn't on the standard library search path.
