[CMake] pkg-config support

Hi,

These are empty, since these are additional flags to be used for the 
target - if you didn't set them, they are empty. You are looking for the 
global variables CMAKE_CXX_FLAGS_DEBUG 
(http://www.cmake.org/cmake/help/cmake2.6docs.html#variable:CMAKE_LANG_FLAGS_DEBUG) 
or similar, look at the global variables here: 
http://www.cmake.org/cmake/help/cmake2.6docs.html#section_Variables%20for%20Languages.

On the other side: These are the flags used to build your library not 
the flags for using you library. This may not be the same flags, or?

Regards,
Werner
