The reason for this is that the games in playground use the 
FindLibKDEGames.cmake file to locate the KDE games library (libkdegames.so). 
This cmake file sets ${KDEGAMES_LIBRARY} to the full path of this library  
and at the linker phase, cmake converts this into -l and -L flags. It was in 
fact me who went through playground and changed the games to link against 
${KDEGAMES_LIBRARY} since this allows playground to be used when kdegames has 
been installed to a non-standard location.

However, while building the games within the kdegames module the 
libkdegames.so library hasn't yet been installed and so cmake links the games 
against the library in the build directory. In this case, cmake knows the 
target of the library is called 'kdegames' and so when you do 
target_link_libraries(gamename kdegames) it knows to link against the local 
copy of the library.

It's really just an artifact of being part of the main module.
