I did the modifications you suggested, but  it still does not work. For 
the include directory, I had to keep
these lines :

*--------------------------

*--------------------------
 even though I did made the modification suggested in cmake file  the 
source directory otherwise, it was not working

Here is my  linker command:

Linking CXX executable ../bin/mdi
cd /Users/program/qtskinmesh/build/mdi && /usr/local/bin/cmake -P
CMakeFiles/mdi.dir/cmake_clean_target.cmake
cd /Users/program/qtskinmesh/build/mdi &&
/opt/intel/cc/10.0.016/bin/icpc     -O3 -mp1 -Kc++ -Dintel
-headerpad_max_install_names  -bind_at_load "CMakeFiles/mdi.dir/main.o"

"CMakeFiles/mdi.dir/moc_csbdmdichild.o"
"CMakeFiles/mdi.dir/qrc_qt4skinmesh.o"   -o ../bin/mdi

ld: warning multiple definitions of symbol _modf
/opt/intel/cc/10.0.016/lib/libimf.a(modf_stub.o) definition of _modf in
section (__TEXT,__text)
/usr/lib/gcc/i686-apple-darwin8/4.0.1/../../..//libm.dylib(xmm_floor.o)
definition of _modf
ld: Undefined symbols:
_tetra_zone_copy_
_xyz_vertex_copy_


and my Undefined symbols are all part of my newly created library 
skinmesh.  What suprrisses me the most is that all that works on fedora 
core 6....

Thanks again,
