Started looking at this, will split over multiple days as it's v big.
If you're able to isolate the relevant discussions for the changes on conda-forge that would be helpful; the links include discussions around historical updates, protobuf, etc. (or do I need to read the whole thing for context..?)

[danpetry]

I can't see where gtest is being used, or the test binaries are being used (beyond checking that they're present)?

[cbouss]

It's for abseil_test_dll, included in this pacakge.

[danpetry]

do the test binaries get run? or does it ship a test suite for use by devs

[cbouss]

libprotobuf does make use of abseil test binaries to built its own test binaries

Tp put it short, all packages depending on abseil must be built with cxx 17 at least. Also, even minor updates can induce breaking changes. The other relevant change is conda-forge renaming the package from abseil-cpp to libabseil.
