The full path was already set. I had read the cmake list archive and 
did all that was previously suggested. Could it be that if you set a 
property on a file, but the file is not used in a 'TARGET' in that 
CMakeLists.txt file, the property is discarded ?

ADD_CUSTOM_COMMAND behaves in just the same way (I just discovered). If 
you use this macro, but none of the OUTPUT files is used in that 
CMakeLists.txt file, the custom command is not added to the makefiles.

I've solved the problem now by using a 'tmp' library as a target in 
that CMAkeLists.txt file. This library is ignored by the rest of the 
build system and the files are then used in a toplevel library.
