What is the semantic of those additions?

This looks like it would now be listed twice in core_implicit_modules, i.e. once more inside the new foreach loop.

Explicitly install byproducts of generating Core dictionaries, and put the CMake code right next to where these byproducts are declared. This is better than relying on all `.pcm` files getting installed via some other part of the CMake code.
Explicitly installing the `modules.idx` file is better than copying it by regex when copying the full library output directory.
Explicitly listing all the `pcm` files that otherwise would not get installed seems tedious, but it has one clear advantage over `install(DIRECTORY ...)`. The problem with the latter is that it copies any subdirectories, not matter if the files in it were matched by regex or not. So what happens is that you end up with several empty directories in the install tree, notably the full directory structure of the Python interfaces, in case they are installed to a different directory. One way to fix this is to install the individual pcm files instead, as suggested by this commit.

Avoid unneeded artifacts in the library installation directory, in particular empty directories if the Python interfaces are installed in a directory other than the library installation directory.
