I was thinking more along the lines of how Homebrew does it:



And you’d write

find_package(Qt 5.12 ...)

With the distro having a FindQt that knows about the versioned packages and will dispatch accordingly.

Or, when building a distro-spesific package foo that depends on qt 5.12, the distro would set CMAKE_PREFIX_PATH to the correct prefix.

I think the latter is what Homebrew does.
