      I have been building Qt successfully for many, many years. For example, on older macOS High Sierra system with Xcode 10 has been doing successful shadow builds of Qt 5.12.x since the middle 2018.

      Well now with the covid-19 my old computer is stuck at the office.

      I have just finished setting up a new iMacPro with macOS 10.15.4 and Xcode 11.4.

      After following the steps to shadow build from git sources I cannot build Qt 5.14.2.

      This is the ERROR that causing chromium and qtwebengine to fail:

      ERROR at //build/config/mac/mac_sdk.gni:80:5: Script returned non-zero exit code.
          exec_script("//build/mac/find_sdk.py", find_sdk_args, "list lines")

      This seems to be some sort of garbage-in-garbage-out error because there the find_sdk.py script should never be given an input of 10.15.4 for an sdk.

      Once we give that same script valid input like 10.15, 10.14 or 10.13 the the output is correct, like so

      The attached file, config_output.zip, contains the config.log, config.opt, config.status and config.summary from my shadow build directory for your review.

      I can send the entire output from the build if necessary.
      We are a commercial customer so please set the priority and label appropriately

      Thanks in advance for your help.
