James Clampffer commented on HDFS-12237:
----------------------------------------
I think the new approach is a pretty reasonable way of handling this. I
noticed you got rid of the PROTOBUF_LIBRARY requirement, was it breaking right
there before even trying to compile the test stub?

> Looks like the PROTOC_IS_COMPATIBLE check fails when Protobuf library is
> built from source. This happens because the check if performed during the
> cmake phase, and the protobuf library needed for this test is build from
> source only during the make phase, so the check fails with "ld: cannot find
> -lprotobuf" because it was not built yet. We should probably restrict this
> test to run only in cases when Protobuf library is already present and not
> being built from source.
