In general, if a package provides a <name>-config program or pkgconfig
(*.pc) files, it's best to use them. (I'm guessing that's what Peter did.=
)

In the case of libusb, you should get the linker flags from "libusb-confi=
g
--libs" (similarly for the includes: "libusb-config --cflags"). If you're
not sure how to integrate this into your build process, check how other
packages do it.
