Building the New Way (cmake)

mkdir -pv build
cmake -B build
cmake --build build
ctest --test-dir build

You can build with different (non-default) compilers by prefixing the first cmake line to set some environment variables, e.g. env CC=clang CXX=clang cmake -B build. These environment variables will not be required in the build step, as they are encoded into the generated files.
