+B<cmake> - CMake (CMakeLists.txt)
+
+=head1 SYNOPSIS
+
+B<dh_auto_*> [B<--buildsystem>=I<cmake>] ...
+
+=head1 DESCRIPTION
+
+CMake is a family of tools designed to build, test and package software. CMake
+generates F<Makefile>s and other temporary files in the build directory from
+the directives present in the F<CMakeLists.txt> and a couple of other build
+system source files. Then a standard set of make targets needs to be executed
+in the build directory to complete source building process. CMake is available
+in the cmake package that is essential throughout the whole build process.
+
+=head1 DH_AUTO NOTES
+
+Out of source tree building is done by default if this debhelper build system
+is selected. This is due to the fact that there is no way to properly clean up
+build directory from temporary files unless it is removed completely.
+Therefore I<clean> step cannot be fully implemented if building is done in
+source. However, the user may still enable in source building by explicitly
+specifying a build directory path that is equal to the source directory path.
