-=head1 NAME
-
-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.
