In C++20, using the result of an assignment to a 'volatile' value is deprecated. Breaking change: register "setter" or modification macros can no longer be used as expressions. Closes https://github.com/espressif/esp-idf/issues/9170
C++ build test
This build-only app can be used to check if certain headers, macros or features can be successfully compiled in a C++ source file.
To add a new test, create a new file main/test_<name>.cpp
and add it to main/CMakeLists.txt.
If you need to check specific compiler flags, use set_source_files_properties
CMake function to adjust the compilation flags for the given source file.
