[llvm] [cmake] Store a list of all possible LLVM_DISTRIBUTION_COMPONENTS

Authored by mgorny on Sep 30 2019, 11:59 PM.



Collect all possible LLVM_DISTRIBUTION_COMPONENTS for a given
configuration, and store them in LLVM_ALL_DISTRIBUTION_COMPONENTS cache
variable. This will make it easier for distribution maintainers to
establish the possible options, and to update them on upgrades.

Actually, this still misses a lot of useful components (such as headers). Help improving it would be welcome.

This isn't really possible to do because CMake doesn't have a mechanism for listing all targets. A more correct approach for this would require generating a ninja build, then you could use ninja -t list to dump all the targets, then you can post-process that list to find a full list of components.

I suppose I'm looking for all the install-* targets. FWICS I can further filter irrelevant 'metatargets' via looking for install-*-stripped.

Hmm, that still misses Sphinx docs (HTML + manpages) and opt-viewer.
