Subject: [PATCH] Allow disabling building filesystem subpackage

cmake-filesystem will be provided by Platform module, other cmake
subpackages by a separate module. Therefore the separate module cannot
provide cmake-filesystem and its packages cannot depend on exact
cmake-filesystem version-release (because release string contains
a "random" hash).

This patch adds a build-condition that allows to build cmake without
cmake-filesystem.
