C++ – Qt Creator – Project ERROR: Xcode not set up properly. You may need to confirm the license agreement by running /usr/bin/xcodebuild

This problem happens when xcode-select developer directory was pointing to /Library/Developer/CommandLineTools when a full regular Xcode was required (happens when CommandLineTools are installed after Xcode)

Solution:

1. Install Xcode (get it from https://appstore.com/mac/apple/xcode) if you don't have it yet.
2. Accept the Terms and Conditions.
3. Ensure Xcode app is in the /Applications directory (NOT /Users/{user}/Applications).
4. Point xcode-select to the Xcode app Developer directory using the following command:
   sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Note: Make sure your Xcode app path is correct.

• Xcode: /Applications/Xcode.app/Contents/Developer
• Xcode-beta: /Applications/Xcode-beta.app/Contents/Developer

Here's what I'm doing:

1) In my framework CMakeLists.txt file, I have the following:

IF (APPLE)
       SET_TARGET_PROPERTIES( MyFramework PROPERTIES FRAMEWORK true)
       SET_TARGET_PROPERTIES( MyFramework PROPERTIES
           XCODE_ATTRIBUTE_INSTALL_PATH @executable_path/../Frameworks/  )
ENDIF (APPLE)

The second "set_target_properties" line configures the framework to always be looked for in the application bundle in the Frameworks sub-folder.

2) In my top-level CMakeLists.txt file, I add setup a unified binary output directory:

SET (CMAKE_LIBRARY_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/Bin)
SET (CMAKE_RUNTIME_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/Bin )
SET (CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/Bin )

3) Then, in my applications' CMakeLists.txt file, I have the following:

IF (APPLE)
       ADD_CUSTOM_COMMAND(
               TARGET MyApp
               POST_BUILD
               COMMAND ${PYTHON_EXECUTABLE}
               ARGS ${CMAKE_HOME_DIRECTORY}/CopyFramework.py
               --binary ${PROJECT_BINARY_DIR}/Bin
               --framework MyFramework.framework
               --app MyApp.app

    )
ENDIF (APPLE)

This calls out to my python script, which does the work of assembling the src and dest paths, and actually copying the Framework.

The final trick is that since this is a Mac only thing, I can rely on an Xcode environment variable within the Python script:

           config= os.environ["CONFIGURATION"]

This allows me to assemble the complete path to the actual binary locations of the framework and the app.

The one thing I wish was that there was a CMake variable that would expand to the current Config within the context of the ADD_CUSTOM_COMMAND... It'd be nice to not have to resort to using the Xcode environment variable.
