How to add none pio ready custom library with lib_dpes

Hi all,

I try to use some of our internal library with platformio with the Lib_deps options. Is it possible to do that ? I put ou Git url with specified with a git tag and from my testing, the .cpp don’t get compiled. Like the title said, those libraries are made in camke system. This don’t matter for now, but i woule like to have platformio build all the cpp file on thoses libraries.

Is that possible wihtout writing the json file ?
