[libcamera-devel] [PATCH v2] meson: Provide build configuration summary

[Kieran Bingham]

Report the enabled pipelines when configuring the meson build hierarchy.

This helps clarify what pipelines are used when building, and is useful
when looking back through build-traces to see what was actually
configured.

This can be expanded upon to report other options, and ideally will be
replaced by mesons summary() functionality when it is available.

I've marked this as v2, as it superceedes the earlier "libcamera:
pipelines: Print enabled pipelines".

This now produces the following output:

...
Program sphinx-build-3 found: NO
Program sphinx-build found: YES (/home/kbingham/.local/bin/sphinx-build)
Configuring config.h using configuration
Message: Enabled pipelines: ipu3, raspberrypi, rkisp1, simple, uvcvideo, vimc
Build targets in project: 86
