[libcamera-devel] [PATCH 3/3] libcamera: Make pipeline handlers selectable at compile time

[Laurent Pinchart]

Add a pipelines project option that specifies which pipeline handlers to
compile in. The corresponding IPA modules are automatically selected.
The default is to compile all pipeline handlers.
