[libcamera-devel] [RFCv1.1 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.
