Head over to the new KDevelop templates section for two KDevelop C templates.

One is using a Makefile to compile and the other CMake.

To use them just copy the archives to  /usr/share/apps/kdevappwizard/templates/ or ~/.kde4/share/apps/kdevappwizard/templates

CMake template: https://sourceforge.net/projects/otzy-007.u/files/cmake_plainc.tar.bz2/download

Makefile template: http://opendesktop.org/content/show.php/Simple+C+Makefile+Template?content=138514
