We are using
find_package in CONFIG mode and our developer instructions require setting
PACKAGE_DIR as the location when running the cmake.
The directory is a git-submodule at a very specific commit we need
(FWIW package is LLVM)
I found that some users who may have the package installed via something such as homebrew on MacOS and cmake is picking up that installation instead.
I am surprised us setting PACKAGE_DIR on the command line is not overriding the search.
Is there something else we should be doing?
