Currently, the release build picks up headers in
`/Library/Frameworks/Mono.framework/Headers`. You can verify this by
downloading the latest nightly build and checking the output of `nvim
--version`.
These headers are likely to be from a different version of `libintl` than the
one we link to. Let's avoid usage of them by setting `CMAKE_FIND_FRAMEWORK` to
`NEVER`.
Having to specify CI_BUILD for every CI job requires boilerplate. More
importantly, it's easy to forget to enable CI_BUILD, as seen by
8a20f9f98a. It's simpler to remember to
turn CI_BUILD off when a job errors instead of remembering that every
new job should have CI_BUILD on.
The universal macos release is particularly sensitive to build system
changes. Adding a job that builds a universal binary whenever a cmake
file is changed will help prevent future release breaks.
