In March 2006, the &cmake; program beat out several competitors and was selected to be the build system for &kde; 4, replacing the autotools-based system that &kde; had used from the beginning. A introduction to &cmake; page is available on the &kde; Community Wiki. Basically, instead of running make -f Makefile.cvs, then configure, then &make;, we simply run &cmake; and then &make;. &kdesrc-build; has support for &cmake;. A few features of &kdesrc-build; were really features of the underlying buildsystem, including configure-flags and do-not-compile. When equivalent features are available, they are provided. For instance, the equivalent to the configure-flags option is cmake-options, and the do-not-compile option is also supported for &cmake; as of &kdesrc-build; version 1.6.3.
