This isn't really an issue with CPack, so CMakeCPack.cmake isn't the
right place to dig around.

The FindQt4 module (which I assume you're using since you're building a
Qt app) should have a variable telling you where the libs are. Then you
can just refer to those as
${QT_LIB_DIR_OR_WHATEVER_IT'S_CALLED}/QtGui4.dll, etc. FindPNG should
have a similar facility.
