CMake Error at qtbase/cmake/QtPublicAppleHelpers.cmake:976 (message):
Qt requires at least version 15 of Xcode, youre building against version .
Please upgrade. You can turn this error into a warning by configuring with
-DQT_FORCE_WARN_APPLE_SDK_AND_XCODE_CHECK=ON, but the build will likely
fail. Use at your own risk.
