Compiling

[Jhynjhiruu]

Trying to compile this - when running make in the directory, I get this error:
cc -g -Wall -Werror `pkg-config --cflags libusb-1.0` -c -o ique.o ique.c /bin/sh: 1: pkg-config: not found ique.c:9:20: fatal error: libusb.h: No such file or directory compilation terminated. <builtin>: recipe for target 'ique.o' failed make: *** [ique.o] Error 1
It seems like the file ique.o is missing...?
