Also please re-release this package with indigo to include the change.
Is there a specific reason why hydro still uses 0.2.22?
If there is not, please release this change in hydro as well.

I have committed a modified fix which also sets Python_ADDITIONAL_VERSIONS before to ensure that versions not available in the CMake config file are found.

Thank you for your response and fix.

Although I don't understand why you did not simply merge the request.
The line you've added (1.) has nothing to do with cmake 3.0 and
(2.) is superfluous as long as you respect your distribution and don't install unsupported versions
in official locations.

Yes, I could have merged the PR first and then added the additional versions line separately. I simply committed them together since it keeps these kind of related changes in a single commit. It was also slightly faster to do it this way since I already had all the changes in my local working copy in order to test it. But anyway I don't see a real difference in both approaches.

And setting the additional versions is by no means superfluous - it is simply not possible to only install a single Python version on most OS I have seen (e.g. Trusty). In order the specific the specific version which should be used (which might not be known to the PythonLibs CMake config file) it must be specified explicitly.

Ok.

It would be great to see this problem fixed in the upcoming indigo-release as well.
However, this requires another release. I don't know whether you expect any more
changes to this module before indigo, but I would like to request this release either way.

This will be released to all active ROS distros: Groovy, Hydro and Indigo.
