Did you try what happens if some of the additional Filter options are
given? Like QDir::Files, QDir::NoDotAndDotDot, QDir::Readable,
QDir::CaseSensitive.

Huh? How did you get to that conclusion? Thats exactly how cmake works,
if libfoo.so is not existing, then the variable is set to -NOTFOUND. 

Try to execute this CMakeLists.txt (adjust the qt-copy path first) after
removing libQtCore.so from qt-copy:

,----
| Find_library(FOO_LIB QtCore
|         PATHS /home/andreas/qt-copy/lib
|         NO_DEFAULT_PATH
|         )
| 
| message("QTCORE: ${FOO_LIB}")
`----
