error: Xcode not set up properly. You ..confirm the license agreement by running /usr/bin/xcodebuild

（1）Xcode版本在8.0以上要安装下面步骤修改。

       >= Xcode 8

          In Xcode 8, as Bruce said, this happens when Qt tries to find xcrun when it should be looking for xcodebuild.

       Step 1:

          Open the file:

      Qt_install_folder/5.7/clang_64/mkspecs/features/mac/default_pre.prf

       Step 2:

          Replace:

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

          With:

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

（2）Xcode版本在8.0以下，按照下面的步骤修改。

      ~> Xcode 8

            Before Xcode 8, this problem occurs when command line tools are installed after Xcode is installed. What happens is the Xcode- select developer directory gets pointed to /Library/Developer/CommandLineTools.

         Step 1:

            Point Xcode-select to the correct Xcode Developer directory with the command:

       sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

         Step 2:

          Confirm the license agreement with the command:

      xcodebuild -license

          This will prompt you to read through the license agreement.

   Enter agree to accept the terms.
