Edit your PRO file LIBS variable to add (or correct) a search path to the QCad library folder.

"qmake - Declaring Other Libraries":http://qt-project.org/doc/qt-4.8/qmake-project-files.html#declaring-other-libraries
"LIBS Variable":http://qt-project.org/doc/qt-4.8/qmake-variable-reference.html#libs

You need to set "LIBS" in your .pro file, assuming you're building on unix :
LIBS += -L/path/to/your/library/ -lqcad

As for win32 (let's link against libmysql that's installed in C:\mysql\lib":
LIBS += C:\mysql\lib\libmysql.lib

Thanks guys, i made it. :-) especially the libs variable link was so helpful.
