There's nothing ecm specific here. The reason I created no such document was because it belongs in (and versioned with) CMake, not in ECM. http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/8144/focus=8147
As that is now possible in cmake master, and as there are other similar manuals in cmake now, consider contributing there instead.

You can link to
http://www.cmake.org/cmake/help/git-master/manual/cmake-packages.7.html
for upstream info on this.

The imported targets should be the primary way of using the module. I don't think the _INCLUDES and _LIBRARIES etc variables should even be set if imported targets are provided.

I don't think AUTHOR_WARNING is appropriate here. Why not WARNING?

Actually it's mostly important so that users can set it in the cache if they have the library in a non-predicted location.

Don't set Foo_VERSION_STRING, set Foo_VERSION. That is canonical because of config-file packages.

Not only convention. CMake also provides a diagnostic if you use '::'.

Note that only build-properties of the target itself should be here. Not those of dependencies (if the dependency provides imported targets, which it should/must for this stuff to work). CMake will resolve that itself.
