If someone will give it a try: For cmake based projects on linux the following
receipt can be used to get an AST (based on the hints at
http://clang.llvm.org/docs/LibTooling.html)
1. unpack  umbrello source into <umbrello-source-dir>
2. mkdir <umbrello-build-dir>
3. cd <umbrello-build-dir>
4. CC=/usr/bin/clang CXX=/usr/bin/clang++ cmake
-DCMAKE_EXPORT_COMPILE_COMMANDS=ON  <umbrello-source-dir>
5. run clang-check -ast-dump -p $PWD
<umbrello-source-dir>/umbrello/umlscene.cpp
