CMake Error: could not find load file /.mbedbuild/mbed_config.cmake

[cyliangtw]

Description

In mbed-tools v5.2.0, it could work on mbed OS v6.7 and generated /.mbedbuild/ folder.
In mbed-tools v7.2.0, suffer could not find load file /.mbedbuild/mbed_config.cmake issue on both of mbed OS v6.7 and last mbed OS master branch.

Error message as below:

[cygwin~mbed-os-example-blinky-cmake]$ mbed-tools compile -m NUMAKER_IOT_M487 -t GCC_ARM

This include is failing include(${MBED_CONFIG_PATH}/mbed_config.cmake)

Can you share what's the value of MBED_CONFIG_PATH ? This is cached variable and it should follow the pattern mbed-os-example-blinky/cmake_build/DISCO_L475VG_IOT01A/develop/GCC_ARM or similar (starting from mbed-tools 7.x).

I am currently working with 7.0.0 locally and latest master and haven't hit this issue with the latest examples (development branch). What's the version of the example you are building (have you updated?) ?

Thanks.
After git pull mbed-os-example-blinky, MBED_CONFIG_PATH is updated and mbed-tools 7.2.0 could work well with OS v6.8 .
However, if I apply the last Mbed OS master branch, cmake build encounter fatal error "can't find core_m4.h", it seems mbed-os/cmsis/CMSIS_5/CMSIS/TARGET_CORTEX_M/Include/ not add into include path.

I fixed the above issue "fatal error: core_cm4.h: No such file" in ARMmbed/mbed-os#14376.

Thank you for fixing this.
