From CMake site:
Generates native build files (e.g., makefiles on Unix; workspaces/projects on MS Visual C++). Therefore, standard tools can be used on any platform/compiler configuration.
Cmake can generate Codeblocks, Eclipse and Xcode projects too.
I’ve created some CMake Build files for Openframeworks. I currently have the libs/openframeworks and im working on the addons. Im open to help create a CMake solution for 0.06. If you are interested in the CMake build files for testing just reply. I promise i will polish them until they fully work on every platform.
I have tested the automated generation of a Kdevelop project, compiled and ran flawlessly.
And i have tested CMake integration within Eclipse Ganymede. It also works fine.
Naturally, i have tested the simple Makefiles generation, and works fine.
