Installs this project's own build artifacts to
out/install/<platform>-<arch>-<compiler>/ (INSTALL_OUTPUT_DIR in
project/Configuration.cmake), scoped to just this project via `cmake --install
--component` -- see the comment at the top of this script.

  --preset <name>  Install the build made with that preset (out/build/<name>).
                   Default: the build breeze/scripts/build.sh made last. Must come
                   first if given at all; --preset=<name> also works.
