We discussed that over the last few months. All relevant information should 
be in these threads:

 http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/5327

 http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/5868/focus=5907

The solution is in cmake master now:

I guess your options are to wait for cmake 2.8.11 to be released (in a few 
weeks) or backport a similar patch to your current cmake version package 
(then re-build all packages using that patched cmake to generate the config 
files).

For clarity, this is not related to cmake being found in /bin. It's about 
where the Config.cmake files are found.

Thanks,

Steve.
