the qmake in path is the one from the 32bit version. All Qt-references
in build/CMakeCach.txt are pointing to the 32bit version.

The final build error I get is:

/usr/local/Qt/5.2.1/lib/libQt5Core.so.5.2.1: could not read symbols:
File in wrong format

So the 32bit Version of Qt is linked, everything else seems to be 64bit.

What is the correct way to define such a build? Maybe I'm missing a
setting. What I do is downloading your gammaray2.0.2,
create a build subdir and there execute a bash script:

export QTDIR=/usr/local/Qt/5.2.1
export QMAKESPEC=/usr/local/Qt/5.2.1/mkspecs/linux-g++-32
export PATH=/usr/local/Qt/5.2.1/bin:$PATH
cmake ..
make
