Yup, that's the scenario. Another possibility would be to use more "-I"
arguments during compilation, then flattening the directory structure in
the #include statements. Then a "-I." would let me build locally.

afaik we rely on file copying rather than simlinks everywhere else, but
if that isn't the case then a simlink here would be just fine.
