 > Only Homebrew installs frameworks in /usr/local/Frameworks.

 If that was the well-founded conclusion of the linked discussion (which I
 haven't had time to scan through) then I suppose it's less dramatic than I
 thought to remove the path. But I'm not so easily convinced that no "semi-
 informed" project would install frameworks into a Frameworks directory
 under its $prefix, nor that there are no users who use /usr/local that
 way. I know I'd be likely to do that myself (instead, I just "trespass" in
 $prefix, using `porg` to keep track of my stuff).

 > a user who wants to find Homebrew-installed frameworks should be using a
 cmake installed by Homebrew, not one installed by MacPorts.

 I cannot agree with that. Again, CMake is NOT a private tool that
 shouldn't be used for any other purpose than to build software destined
 for installation in $prefix or using only dependencies under $prefix. Why
 would it be made difficult for users who have a HB install in addition to
 MacPorts because of stuff that's not available in MacPorts?

 Now, if `/usr/local/Frameworks` is in `CMakeFindFrameworks.cmake`
 *because* HomeBrew uses that path, then an argument could be made
 (upstream!) that the search should include `$prefix/Framework` (I suppose
 that would be `${CMAKE_SYSTEM_PREFIX_PATH}/Frameworks`). Being more
 generic that should logically come before the hardcoded path, but that
 could always be corrected in a patchfile.
