esp32-c3 build fails with unknown CMake command "add_prebuilt_library"

[nliviu]

After the latest commit as of 22/02/2023 build for esp32c3 fails

CMake Error at /mongoose-os/platforms/esp32xx/esp32xx.cmake:11 (add_prebuilt_library):
  Unknown CMake command "add_prebuilt_library".

It looks like /mongoose-os/platforms/esp32c3/CMakeLists.txt is missing

include($ENV{IDF_PATH}/tools/cmake/project.cmake)

@a2800276 can you check and put up a fix please?

[a2800276]

Ah yes, didn't copy over to esp32c3, sorry.
Let me try to set up a mini project to build for both plattforms.

[a2800276]

Ok, I've copied the CMakeFiles.txt and tested it: #606

I'm not sure how you guys typically go about testing the build. I tried building demojs app for esp32 and esp32c3 before and after, before esp32 worked and c3 failed, after both build suceeded.

Thank you!

No worries, I should have tested the PR before submitting. Sorry about being the elephant in the china shop in the first place :)
