Error finding a .pb.o file externally

[Jon Godbout]

Hey all,

I'm trying to get the cl-protobufs protoc to compile externally debending on ABSL and Protocol buffers. 

I have this pull request which installs absl and protobufs from source.

https://github.com/qitab/cl-protobufs/pull/438

Then I get:
