[CMake] CMakeModules repository at GitHub?

[David Cole]

Qt is actually the perfect example of this. Stephen Kelly has done a 
superb job getting project config files working with Qt 5. That's right 
-- you can actually do a find_package of Qt for Qt 5 with an existing 
CMake release, *without* having a FindQt5.cmake file in CMake itself. 
It's awesome!

Good idea, Bill to add to the module maintainer wiki page suggesting 
that they first attempt adding a project config file, using Qt 5 as a 
very good example.

Well, put.  I like everything said here.  I am thinking maybe we should
update the ModuleMaintainers wiki entry to include instructions on how
to create and contribute a cmake config file to a non-cmake project and
suggest that that is done first.   Maybe it should be a requirement for
any new CMake module that you show that you tried to get a config file
upstream first and failed.  We might still need the module for older
versions of the software, but perhaps the job of the CMake module
maintainer needs to be expanded to include creating and submitting a
cmake config file into the upstream project.

This is a much smaller job than converting a whole project to cmake, 
and
works very well even in non-cmake based projects.
