From the build framework's/compiler's POV, it should look in
/usr/pkg/include (etc.) for the headers like usual. pkgsrc's
buildlink3 framework intercepts the compiler command line and rewrites
it to look in ${WRKSRC}/.buildlink instead.

So there should be no reason to tell anything in the build framework
to look in ${WRKSRC}/.buildlink directly.

Please check that
- the wanted headers are there
- the proper -I/usr/pkg/ flag is on the compiler command line
- the proper compiler is used and the command is rewritten (see work/.work.log)

Cheers,
