In my case it happened, not because I hadn't specified a location to Xcode, but because I was using Xcode 8.

It's a weird behaviour, because in my case /usr/bin/xcrun existed all right, but it was not included in /Applications/Xcode.app/Contents/Developer/usr/bin. In previous versions of Xcode, that directory contained xcrun, but not in Xcode 8, at least not on my version of Mac OS X.

I tried creating a symbolic link there, pointing to /usr/bin/xcrun, but it didn't solve the problem.

The only solution I found was to change the code that was triggering the error, by replacing /usr/bin/xcrun -find xcrun with /usr/bin/xcrun -find xcodebuild.

I think it is a pretty safe thing to do, since this command aims at checking that Xcode is correctly installed is set up, thus the new command does the job. Reassuringly, that' what Qtbase did: https://code.qt.io/cgit/qt/qtbase.git/commit/?h=wip/nacl

Looks like this was the problem. > 1 version of xcode installed. XCODE / PREFERENES / LOCATIONS / COMMAND LINE TOOLS. Selected the proper one, it was blank when not working even after installed a new version of the tools.
