The compiler provided by the above LLVM package should be used in place of the
one provisioned by XCode, which does not support the multithreading library used
by OpenMC. Consequently, the C++ compiler should explicitly be set before
proceeding:

.. code-block:: sh

export CC=/usr/local/opt/llvm/bin/clang
export CXX=/usr/local/opt/llvm/bin/clang++
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"
by OpenMC. To ensure CMake picks up the correct compiler, make sure that either
the :envvar:`CXX` environment variable is set to the brew-installed ``clang++``
or that the directory containing it is on your :envvar:`PATH` environment
variable. Common locations for the brew-installed compiler are
``/opt/homebrew/opt/llvm/bin`` and ``/usr/local/opt/llvm/bin``.

After the packages have been installed, follow the instructions to build from
source below.
