To prevent complicating the dependencies of a core tool, a new variant,
CMAKE-MINIMAL is introduced and the CMake build system is configured to use it
by default. The regular CMAKE package gains a manpage, info manual as well
as HTML documentation.
Fixes issue #33497 (https://bugs.gnu.org/33497).
* gnu/packages/cmake.scm (gnu): Use modules (gnu packages python-xyz),
(gnu packages texinfo) and (srfi srfi-1).
(cmake-minimal): Rename the original cmake variable to this.
[phases]{configure}: Extract the configure script arguments to...
[configure-flags]: here.
[properties]: Set the HIDDEN? property to #t.
(cmake): New variable, which inherits from CMAKE-MINIMAL.
[phases]{move-html-doc}: Add phase.
[native-inputs]: Add PYTHON-SPHINX and TEXINFO.
[outputs]: Add the "doc" output.
[properties]: Clear the inherited HIDDEN? property.
* guix/build-system/cmake.scm (default-cmake): Use CMAKE-MINIMAL instead of
CMAKE.
