Cannot compile ESP BLE MESH with CPP/C++ (IDFGH-11072)

[heculess]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.1

Operating System used.

Windows

How did you build your project?

Command line with Make

If you are using Windows, please specify command line type.

CMD

What is the expected behavior?

compile complete

What is the actual behavior?

compile failed

Steps to reproduce.

cd ble_mesh_sensor_model\sensor_server
change main.c to main.cpp
change main.cpp to compile with C++
get error

I have the same issues with 5.1 and 5.2, but its has been solved/fixed in v5.3 (master), hopefully for good.
