Hi, we at XinaBox has developed extension for SD card which uses .cpp files, the extension is dependent of mbed libraries. The extension works fine in online [microbit.makecode.com](http://microbit.makecode.com) editor, but the build fails in Github CI. The extension also builds fine when built locally using command line.

Complete build: [https://github.com/xinabox/pxt-IM01/runs/1278270783?check\_suite\_focus=true](https://github.com/xinabox/pxt-IM01/runs/1278270783?check_suite_focus=true)

Seems that the error comes after pxt-micorbit version 3.0.22. Please can someone confirm if pxt-microbit has removed “mbed.h” file after the version 3.0.22. Many thanks

Is that the same as: [https://github.com/microsoft/pxt-microbit/issues/3506](https://github.com/microsoft/pxt-microbit/issues/3506) ?

I am not sure, but I can say that our other extensions using cpp files are building fine. This particular one is causing trouble due to “mbed” cpp files added.
