How do I install Roccat Vulcan 100 keyboard driver for light effects?

[Here's the driver (it is called a "driver", isn't it?) for keyboard backlight](https://github.com/duncanthrax/roccat-vulcan) . I'm mostly interested in playing with the source code to understand something more about drivers, if possible. However, before diving into the code, I'd like to install it and see it working. That way I could really loop on "edit-reinstall-try" to see what effect my changes have. Well, I'm blocked at square 1, as I haven't been able to install the driver. To be honest, I haven't tried running sudo make install, and before doing so, I'd like to understand whether I truly need it and, if I do need it, understand why. I see that the [Makefile](https://github.com/duncanthrax/roccat-vulcan/blob/master/src/Makefile) has this install target:

install:
	mkdir -p ${DESTDIR}${BINDIR}
	cp $(NAME) ${DESTDIR}${BINDIR}/
	mkdir -p ${DESTDIR}${UDEVDIR}
	cp *.rules ${DESTDIR}${UDEVDIR}/

and a few lines above there's

BINDIR  := /usr/bin

so it's clear to me that sudo privileges are required because DESTDIR is not set, so ${DESTDIR}${BINDIR} resolves to /usr/bin, which needs sudo to be written to. However, if there's a ${DESTDIR} prefix in the first place, I wonder why I shouldn't run make install DESTDIR=$HOME or something. Indeed, I tried, but the executable, roccat-vulcan, when run, errors with Unable to find keyboard. Maybe it does need to be installed in /usr/bin? --- [A related question.](https://unix.stackexchange.com/questions/25715/why-do-some-packages-use-make-install-while-other-use-sudo-make-install) --- **Update** As suggested in the answer, I've tried installing with sudo make install BINDIR='/usr/local/bin', which succeed with the following **_output_**:

mkdir -p /usr/local/bin
cp roccat-vulcan /usr/local/bin/
mkdir -p /etc/udev/rules.d
cp *.rules /etc/udev/rules.d/

However, trying to run the software gives error. Below the output of roccat-vulcan -v:
