We have two configure options related to libconfig: 1) --disable-gadget-schemes 2) --without-libconfig Option #1 means that libusbgx itself should be compiled without gadget schemes support. Option #2 means that everything what requires libconfig should be turned off. So option #2 is wider than #1 as libconfig us used also in our testing program. To fix this meaning let's use HAS_GADGET_SCHEMES inside library source code to determine if we should use libconfig or not and HAS_LIBCONFIG inside our tests source code.
