It will try to find plugins without the full path. It does require ICEmu to be compiled and in the ../build directory.
Default plugin paths are (relative to this directory):
../example-plugins
../plugins
Other paths can be added using the ICEMU_PLUGIN_PATH environment variable using
absolute paths separated by a colon e.g.,
export ICEMU_PLUGIN_PATH="/home/user/newpath/to/plugins:~/relative/to/home/is/ok:$ICEMU_PLUGIN_PATH"
