Awesome for C++ IDE
kdevelop is good and fat and, more interesting, is the ticket to the exciting world of kde community
This is a very powerful all in one IDE
This is the only IDE I have ever found that can do this. I've been struggling to import a cmake project to Eclipse CDT (debugging is not working and spent a whole day trying to fix it), CodeBlocks (code completion SUCKS!) and Monodevelop can't import a cmake project. KDE is the best I have ever found.
