Pre-defined compiler flags are not picked up when importing .cproject file

[lukas-lang]

Type: Bug Report

Describe the bug

• OS and Version: Ubuntu 20.04
• VS Code Version: 1.78.2
• Embedded Tools Extension Version: 0.7.0
• Target embedded device: -
• RTOS version: -
• Other extensions you installed (and if the issue persists after disabling them): -
• A clear and concise description of what the bug is: When importing a .cproject file, the predefined compiler flags are not picked up. This includes e.g. the warning flags -Wall, -Werror, ... as well as the C++ standard selection: Importing the above project results in the following flags in the CMake file:

  target_compile_options(
    ${TARGET_NAME} PRIVATE
    "$<$<AND:$<CONFIG:Debug>,$<COMPILE_LANGUAGE:ASM>>:-g3>"
    "$<$<AND:$<CONFIG:Debug>,$<COMPILE_LANGUAGE:C>>:-g3>"
    "$<$<AND:$<CONFIG:Debug>,$<COMPILE_LANGUAGE:CXX>>:-g3>"
    "$<$<AND:$<NOT:$<CONFIG:Debug>>,$<COMPILE_LANGUAGE:ASM>>:-g0>"
    "$<$<AND:$<NOT:$<CONFIG:Debug>>,$<COMPILE_LANGUAGE:C>>:-g0>"
    "$<$<AND:$<NOT:$<CONFIG:Debug>>,$<COMPILE_LANGUAGE:CXX>>:-g0>"
    "$<$<AND:$<NOT:$<CONFIG:Debug>>,$<COMPILE_LANGUAGE:C>>:-Os>"
    "$<$<AND:$<NOT:$<CONFIG:Debug>>,$<COMPILE_LANGUAGE:CXX>>:-Os>"
    "$<$<AND:$<CONFIG:Debug>,$<COMPILE_LANGUAGE:C>>:>"
    "$<$<AND:$<CONFIG:Debug>,$<COMPILE_LANGUAGE:CXX>>:>"
    "$<$<AND:$<NOT:$<CONFIG:Debug>>,$<COMPILE_LANGUAGE:C>>:>"
    "$<$<AND:$<NOT:$<CONFIG:Debug>>,$<COMPILE_LANGUAGE:CXX>>:>"
    "$<$<CONFIG:Debug>:-mcpu=cortex-m4>"
    "$<$<CONFIG:Debug>:-mfpu=fpv4-sp-d16>"
    "$<$<CONFIG:Debug>:-mfloat-abi=hard>"
    "$<$<NOT:$<CONFIG:Debug>>:-mcpu=cortex-m4>"
    "$<$<NOT:$<CONFIG:Debug>>:-mfpu=fpv4-sp-d16>"
    "$<$<NOT:$<CONFIG:Debug>>:-mfloat-abi=hard>"
  )

To Reproduce Steps to reproduce the behavior:

1. Create a new project in STM32CubeIDE
2. Go to Project > Properties > C/C++ Build > Settings > MCU G++ Compiler
3. Select some of the warning flags or a C++ standard
4. Run the code generation
5. Import the .cproject file into VS Cod
6. Note the flags are not present in cmake/st-project.cmake

Expected behavior The flags should be recognized and reflected in the generated cmake file
