build: fatal error: absl/hash/hash.h not found

[spendres]

When running ./test.sh on MacOSX12.6 →
#8 8.141 ../third_party/s2geometry/src/s2/s2point.h:21:10: fatal error: absl/hash/hash.h: No such file or directory
#8 8.141 #include "absl/hash/hash.h"

Does radar have updated docker build files that use abseil-cpp as a github submodule? Or updated CMakeFiles used for in-house builds?

This happens if the git submodule hasn't been pulled in. I've updated ./test.sh in this PR to fix this: #59
