CAChannel Wrapper: optionally use p4p instead of CaChannel #8359

Open rerpha opened 1 month ago

rerpha commented 1 month ago

As a developer I would like anything that uses our CaChannel wrapper to be able to "speak" PV access. as we have an abstraction layer this should be somewhat simple.

This follows on from https://github.com/ISISComputingGroup/IBEX/issues/8358

Acceptance criteria

Note: make sure we don't end up loading multiple versions of channel access libraries. p4p likely uses epicscorelibs by default, CaChannel uses our own build. May need a custom build of p4p to ensure it uses the same underlying libraries as CaChannel.
