I tried some of that ... but with no great success ...

Below is the original link command with static qt libraries ...

I tried to do - as you did in your example, ant that is my new link command
(in comparison to the one below) (When linking with this one the file gets a
little smaller - around 500 kb.): 

/usr/bin/c++    -frounding-math -g   -Wl
CMakeFiles/Pseudo_triangulation_2.dir/src/Pseudo_triangulation_2.o
CMakeFiles/Pseudo_triangulation_2.dir/qrc_Pseudo_triangulation_2.o -o
Pseudo_triangulation_2 -Bstatic -L/usr/local/lib
/usr/local/lib/libCGAL_Qt4.a /usr/local/lib/libCGAL.a -Wl,-Bstatic
-lboost_thread-mt -Wl,-Bstatic
/usr/local/Trolltech/Qt-4.7.0/lib/libQtOpenGL.a -Wl,-Bstatic -lGLU
-Wl,-Bdynamic -lGL -Bstatic /usr/local/Trolltech/Qt-4.7.0/lib/libQtGui.a
-Wl,-Bstatic -lpng -lSM -lICE -lXrender -lfreetype -Wl,-Bdynamic
-lfontconfig -Wl,-Bstatic -lXext -lX11 -Wl,-Bstatic
/usr/local/Trolltech/Qt-4.7.0/lib/libQtCore.a -Wl,-Bstatic
/usr/local/Trolltech/Qt-4.7.0/lib/libQtCore.a -Wl,-Bdynamic

There are a couple of questions:
1. Is it right to (only) deal with the command under: "Linking CXX
executable Pseudo_triangulation_2", or can there be any dependencies with
the other files/commands? (I don't think so as they are qt specific, is this
right?)
2. Is there a way to see which libraries cause the dynamic linkages? Or is
it just the dynamic link with lGL (I think this will be OPENGL) and
fontconfig? What does the last -Wl, -Bdynamic mean (this is necessary - it
is not working without this)?
3. And the most important question: Does anyone see a way around these
dependencies? :-)

Best
Pascal
