CMake IDE/TPL added

[xeno010]

This is very helpful when working with cmake without a specific IDE.

# Create new cmake project
platformio init --ide cmake --board <ID>

11 predefined targets for building

PLATFORMIO_BUILD - Build project without auto-uploading
PLATFORMIO_BUILD_VERBOSE - Build project without auto-uploading in verbose mode
PLATFORMIO_UPLOAD - Build and upload (if no errors)
PLATFORMIO_CLEAN - Clean compiled objects
PLATFORMIO_MONITOR - Device monitor platformio device monitor
PLATFORMIO_TEST - PIO Unit Testing
PLATFORMIO_PROGRAM - Build and upload using external programmer (if no errors), see Upload using Programmer
PLATFORMIO_UPLOADFS - Upload files to file system SPIFFS, see Uploading files to file system SPIFFS
PLATFORMIO_UPDATE - Update installed platforms and libraries via platformio update
PLATFORMIO_REBUILD_PROJECT_INDEX - Rebuild C/C++ Index for the Project. Allows one to fix code completion and code linting issues.
PLATFORMIO_DEVICE_LIST - List connected devices.

I use it on two big projects and it works great. I hope you'll add it for everyone.

Have you seen platformio init --ide clion? You can write a script which generates project for CLIon and then removes not used CLIon related files

Sure, but I'd have to delete the .idea folder every time even if I only call cmake PLATFORMIO_REBUILD_PROJECT_INDEX (->pio -f -c clion init --ide clion)

second problem:
PLATFORMIO_REBUILD_PROJECT_INDEX (-> pio -f -c clion init --ide clion) does not work properly in clion. It overwrites each time the files workspace.xml, watcherTasks.xml and modules.xml in the .idea folder. This means that all my custom file guards, my custom settings etc are deleted and I have to restart clion every time.

I develop in CLion and i use pio -f -c cmake init --ide cmake instead of pio -f -c clion init --ide clion(for rebuilding index) which only updates CMakeLists.txt and CMakeListsPrivate.txt.

This will also solve #2990, because if CMAKE_EXPORT_COMPILE_COMMANDS is set (env or in CMakeLists.txt), cmake will generate compile_commands.json for us.

All committers have signed the CLA.

We implemented #2990

What is a reason to use cmake wrapper around our CLI? We are on the way dropping support for CMake because of these are overheads.
