Answer 1

Run MaintenanceTool in Qt directory and update to version 5.8

Answer 2

I managed to get capybara-webkit (which uses QT) built with XCode 8 / MacOX Sierra after following these instructions (found here: https://forum.qt.io/topic/71119/project-error-xcode-not-set-up-properly/7)

1. Move to the folder where you install Qt.
2. Open in a text editor the file at Qt_install_folder/5.7/clang_64/mkspecs/features/mac/default_pre.prf

3. Find the line with text (for me it was line 15):

   isEmpty($$list($$system("/usr/bin/xcrun -find xcrun 2>/dev/null")))): \
   

   Replace line with:

   isEmpty($$list($$system("/usr/bin/xcrun -find xcodebuild 2>/dev/null"))): \
   

4. Save & re-compile

Answer 3

A cleaner solution

cd /Applications/Xcode.app/Contents/Developer/usr/bin/
sudo ln -s xcodebuild xcrun
