So let's say I have  
src/main/CMakeLists.txt 
src/main/sub/CMakeLists.txt 
build/main/ 
build/main/sub/ 
 
When creating the project files for main/sub/CMakeLists.txt I need the
directory 
"src/main/" (to enter it as project dir in foo.kdevelop). To get it I
currently use  
getPorperty("PROJECT_SOURCE_DIR"). 
I also need "build/main/sub/" since this is the place where foo.kdevelop and

foo.kdevelop.filelist are created. For this I use currently
StartOutputDir(). Seems 
to work. It shouldn't matter from which directory cmake was started (i.e.
whether 
explicitely by calling cmake from the main/ dir or implicitely by calling
make later 
on). It seems to do what I want. 
 
I also didn't understand how RelativePath() works. 
If I had e.g. /usr/src/test/blah/foo.cpp and as directory /usr/src/, it
returned 
../test/blah/foo.cpp. This is not what I expected ( test/blah/foo.cpp). 
 
Bye
