[CMake] cmake cannot find headers and libraries

I am using cmake to build stage. <http://playerstage.sourceforge.net> But
cmake is not able to find some dependencies. I have compile *libpng* myself,
so I dont have the pkg-config files. The *pkg_search_module* function is
being used to search that library. Isnt there any option to explicitly
define the library, and include directory path for libpng? Also, it is not
able to find the *playercore *library. It has the pkg-config files in some
location, whose path I have added to the PKG_CONFIG_PATH variable. Does it
have anything to do with pkg-config executable? ( I am using pykg-config
dont know why)
Stage version 4.0.1
