Meta: Use CMake functions to extract files

Browse source 
Newer cmake's have internal functions to un-compress files. These
functions will work on pure windows - as well as linux. This
eliminates the need to search for external tools (TAR,GZIP,ZIP) - and
helps fixing #9866.

In order to finally fix #9866 we need to decide to bump the cmake
version requirements and remove the checks. If we demand a newer cmake
version, we will loose Ubuntu 20.04 as a build target - as it ships
with CMake 3.16.

For now - we keep compatibility with CMake 3.16 - and only if CMake
3.18 as been found - we use its new functionality.
