make cmake profiles selectable

[jshjs11]

This is a really great tool for cmake projects!
Could you make for us to select a one profile between multiple cmake profiles such as the following example?

e.g.) It would be very useful if we can select 'cmake profile A' or 'B' in the command palette.

"cmake": [
    {
        "name": "cmake profile A"
        "build_folder": "$folder/build-A",
        "env": {
            "CC": "clang",
            "CXX": "clang++",
            "ENV_A": "AAA",
        },
        "command_line_overrides":
        {
            "CMAKE_BUILD_TYPE": "Debug",
            "CMAKE_EXPORT_COMPILE_COMMANDS": true,
        },
        "cmake_debug": true,
    },
    {
        "name": "cmake profile B"
        "build_folder": "$folder/build-B",
        "env": {
            "CC": "/opt/local/bin/arm-none-eabi-gcc",
            "CXX": "/opt/local/bin/arm-none-eabi-g++",
            "ENV_B": "BBB",
        },
        "command_line_overrides":
        {
            "CMAKE_BUILD_TYPE": "Debug",
            "CMAKE_EXPORT_COMPILE_COMMANDS": true,
            "CMAKE_TOOLCHAIN_FILE": "/opt/local/share/arm_toolchain.cmake",
        },
        "cmake_debug": true,
    },
]
