That is why you need config.h file, to enable/disable optional features
as suitable. For example DirectWrite and Uniscribe backends should be
disabled by default since they are only for testing purposes (comparing
HarfBuzz output to MS implementations) and are not needed in production
code.

Or may be the issue is that you are using your own build system and just
included all the source files, in this case you can just skip
hb-directwrite.* and hb-uniscribe.* (among others, reading
src/Makefile.am should give some clues).
