Hi,

I investigated my problem further and I noticed that find_package only finds the config file if located on a specific location depending on enabled languages:
- no languages enabled:               /usr/lib/cmake/bar/BarConfig.cmake
- at least one language enabled:   /usr/lib64/cmake/bar/BarConfig.cmake

So selected languages have an impact on the searched library path : it takes the arch into account if one is enabled.

My box is a Fedora 18 x86_64 with latest cmake 2.8.10.
Should I report it ?

M.
