Version: (using Devel) Installed from: Compiled sources To reproduce: - open any kind of template e.g. Qt + GUI - symlink some other folder into your project - add that folder==symlink via add_subdiractory (or marcro_optional_...) - open some file inside the symlinked folder that includes e.g. Qt stuff result: all build-dirs are fubar, "no Makefile in $symlinkeddir".
I don't think this is relevant anymore, with hindsight at the CMake support in KDevelop 5.
