Meta: Error out on find_program errors with CMake less than 3.18 We have seen some cases where the build fails for folks, and they are missing unzip/tar/gzip etc. We can catch some of these in CMake itself, so lets make sure to handle that uniformly across the build system. The REQUIRED flag to `find_program` was only added on in CMake 3.18 and above, so we can't rely on that to actually halt the program execution.

#
# Check for the dependencies that the Serenity (target) and Lagom (host) builds require.
#
# FIXME: With cmake 3.18, we can change unzip/untar/gzip steps to use
# file( ARCHIVE_EXTRACT) instead
#
# Additionally we have to emit an error message for each tool,
# as REQUIRED only works with cmake 3.18 and above.
Meta: Use CMake functions to extract files 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.

Meta: Do not log CMake version on each CMake invocation It is a tad verbose to print this each time CMake runs.
