I would like to use EDE (from CEDET) to handle some of my C++-projects that are based on cmake. I found some information that this should be possible. But what's the best way to create a new project from existing source and cmake files?
CMake-based projects aren't supported yet natively - I personally use standard ede-cpp-root project type + some custom commands to compile code. There is some work on more complete functionality in this direction. You can find changes in separate repository.
