CMake Error: include_directories given empty-string as include directory

[claui]

When I try to install hwang (either via brew install scanner-research/homebrew-scanner/hwang or automatically as a dependency of scanner), I get the following error:

I faintly remember version 0.3.3 used to install successfully but I’m not entirely sure.

Looks like it's not finding GoogleTest:

-- Could NOT find GOOGLETEST (missing: GOOGLETEST_INCLUDE_DIR GOOGLETEST_LIBRARY) 

I'll look into this.

@claui I think this is fixed now. Can you try to reinstall?

[claui]

@apoms Works for me now 👍

Thanks @apoms!
