Good start.  Please reverse the order of the commits to convert to
the nested conditions first.  That will make the logic change in
the second commit easier to follow.

Also please update the test suite.  Some existing tests may need
updates (though I haven't checked).  Also we should add a test for
this use case in `Tests/RunCMake/find_package/RunCMakeTest.cmake`.
The RunCMake infrastructure allows us to check CMake's output.
One can add a test that searches for a DoesNotExist package to
verify the error message.

Please open a merge request for this as `CONTRIBUTING.rst` explains.

Thanks,
