The one location is the CMake install tree (see :func:`.constants.CMAKE_INSTALL_DIR()`). Why ? This is a necessary evil because ``Setuptools`` keeps track of packages and modules files to install using a dictionary of lists where the key are package names (e.g ````) and the values are lists of module files (e.g ``['', '']``. Since this doesn't allow to "split" files associated with a given module in multiple location, one location is selected, and files are copied over. How? It currently searches for modules across both locations using the :class:`.utils.PythonModuleFinder`. then with the help of :func:`_package_data_contain_module`, it identifies which one are either already included or missing from the distribution. Once a module has been identified as ``missing``, it is both copied into the :func:`.constants.CMAKE_INSTALL_DIR()` and added to the ``package_data`` dictionary so that it can be considered by the upstream setup function.
