The dependencies are libusb, libavahi-client and libavahi-common (and pthread and stdc++)
The PREFIX environment variable defines where the compile is going to look for libraries. This defaults to /usr which is fine when compiling on the same machine as you're gonna run it.
If using a cross-compiler, be sure to set PREFIX to the appropriate path with the target machine's libraries, and set the CROSS_COMPILE environment variable to whatever leads up to the c++ compile binary.
On ubuntu, install the dependencies using
sudo apt install libusb-1.0.0-dev libavahi-client-dev libavahi-common-dev
then run
make
On macOS, we don't use avahi but dnssd for the zeroconf feature. There you run
make DNSSD=1
When cross-compiling for OpenWRT, I used the following lines to set the environment
export OPENWRT_PATH=~/labnation/openwrt/openwrt/
export STAGING_DIR=$OPENWRT_PATH/staging_dir
export CROSS_COMPILE=${STAGING_DIR}/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/bin/mipsel-openwrt-linux-uclibc-
export PREFIX=`realpath $STAGING_DIR/target-*uClibc*/usr/`
then run
make
