KDevelop gets all include files from the build manager.  You probably don't 
have a build directory assigned in your cmake configuration for the kdevelop 
project, which is needed for cmake support to get the include directories.

BTW, this is the real bug - that a) we don't request the build directory at 
project import time, and b) that we don't show a warning somewhere that the 
cmake support is incompletely configured.

See above, once it's configured, everything should work flawlessly, whether 
the includes are within the project or not.
