Step #5: T+743.963s [444/511] Generate compute HTML documentation
Step #5: FAILED: google/cloud/compute/CMakeFiles/compute-docs /workspace/cmake-out/google/cloud/compute/CMakeFiles/compute-docs

Unfortunately there was no further error output, and my initial investigation indicates that it is all hidden by CMake's doxygen_add_docs() function.

Let's at least file this issue to track if it recurs.
