Qt on OS X with just command line tools?

[Martii]

Had to go hunting elsewhere for the solution since it's definitely not present here. :)

Detect current version PATH for Xcode with this:

$ xcode-select --print-path
/Applications/Xcode.app/Contents/Developer

... which means where the Apple App Store downloaded it to was in the wrong place... so copy (or move) Xcode to /Applications and then qmake actually works without the nagging license.

Change it, if necessary, with:

$ sudo xcode-select -s /Applications/Xcode-Beta.app/Contents/Developer
