[libcamera-devel] [RFC PATCH] ipa: meson: Install mojom generated headers to include paths

[Umang Jain]

Generated IPA headers from mojom files need to be installed sy
$INCLUDE_PATH in order to be available system-wide. Without this,
out-of-tree IPAs won't be able to link and build themselves.

Marked as RFC to discuss:
- Whether it makes sense to provide -ipa_serializer.h
  and -ipa_proxy.h system-wide too? I am not 100%s sure yet.
