function(generateInstallTargets)

looks like what I’d expect to see in

make install

. It’s putting stuff into install locations. The part that becomes hard for me is what happens next.

function(generatePackageTarget)

sets a bunch of cmake variables and then passes it off to

include(CPack)

I think? Which is a black box. So when I look at something like the install permissions error, I have no idea how to fix it. And I’m at the mercy of whatever variables the cpack developers exposed.
