That is correct, this doesn't affect the workflow at all. The only difference is that you'll notice that we install the library to a fake location and the paths that we use for testing (e.g. to refer to `include/c++/v1`) are slightly different, since they point to the "fake installation root" instead of pointing within the build directory.
