I just stumbled on the same error while trying to run make. I managed to get it to work following the solution I found here: In the pango-coverage.h and pango-fonts.h files I changed the lines #include <hb.h> to #include <harfbuzz/hb.h>. Probably quite a bit too late for the creator of the issue, but if someone should stumble on the same issue this is how I managed to fix it.
