Comment:
hi @biopsin do you mean:

```
make_build_args="LOCALINC=${XBPS_CROSS_BASE}/usr/include
 LOCALLIB=${XBPS_CROSS_BASE}/usr/lib
 FREETYPEINC=${XBPS_CROSS_BASE}/usr/include/freetype2
 X11INC=${XBPS_CROSS_BASE}/usr/include/X11
 LDFLAGS+=\$(LIBS) CFLAGS+=\$(INCS)"
```

This works but I feel like this is more indirect and implicit than just setting up CFLAGS/LDFLAGS directly which is the desired effect.

```
CFLAGS="-I${XBPS_CROSS_BASE}/usr/include"
CFLAGS+=" -I${XBPS_CROSS_BASE}/usr/include/X11"
CFLAGS+=" -I${XBPS_CROSS_BASE}/usr/include/freetype2"
LDFLAGS="-lfontconfig -lXft -lXinerama -lX11 -lImlib2"
```

Perhaps @ericonr can weigh in.
