[CMake] FindOpenEXR.cmake inclusion in cmake modules?

[David Cole]

First, ask if the module is really necessary. If, instead, you can add an
OpenEXRConfig.cmake file to the OpenEXR project itself, and install it in a
place that cmake's find_package will automatically find it, then a find
module is unnecessary.

However, if that's not possible or practical, then...

Follow the directions here on becoming a module maintainer:

If anything is unclear, ask here for clarification.


Thanks,
David
