Hello, I would like to write some FindFoo.cmake files to find packages installed on different systems including Mac. I have noticed that homebrew install packages in a repertory whose name depends on the version of the package. For example, I have installed a scientific library called scotch, and it is now installed here: /usr/local/Cellar/scotch/6.0.4_4
You should never need to use the Cellar directories directly. It should also be linked under /usr/local/opt/scotch *and* linked directly into /usr/local.
When writing a FindFoo.cmake file, you shouldn't need to do anything special to handle this. Just find the headers and libraries as usual.
If it's linked into /usr/local (brew link scotch) then it should be picked up without any special action
If it's not linked into /usr/local then the user should be able to add /usr/local/opt/scotch (or /usr/local/Cellar/scotch/nnnn) to CMAKE_PREFIX_PATH and it should then be picked up, again with no special casing in your FindFoo script
