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.
