Subject: Export: Fix internal CMake version test logic
Fix the internal DEVEL_CMAKE_VERSION macro to use CMake_VERSION_ENCODE
to compare version component-wise. Otherwise an old invocation of the
macro may be tricked into using the current version when the requested
major version is smaller than the current version but the requested
minor version is larger. It should use the requested (old) version in
that case.
