So I have a top-level `CMakeLists.txt` authored by “us” (our company) and plenty of subordinate `CMakeLists.txt` files which were mostly not authored by us.
Most of these contain an `install()`. Seemingly dozens if not hundreds of components.
Now all the advice I found on how to deal with this told me to pass `--component`. So I thought: well, this can’t be that hard. First I tried the target name, but apparently that’s a separate concept. And in script I wasn’t able to find whether there was a list of components to output.
So my question is: how can I get the component names from within a given build directory? What I was hoping for is something akin to `cmake --install . --component list` (or whatever other reserved word could be used to see the list). … without having to scour all of these “other” `CMakeLists.txt`, which isn’t trivial.
Thank you!

**AFAIK** : It works with `Unix Makefiles` only yet:
```bash
bash-5.3$ make list_install_components
Available install components are: "beman.exemplar" "beman.inplace_vector"
bash-5.3$
```
