rpath that allows searching library relative to its location

rpath.md

source

We can use the $ORIGIN "special" path to have a path relative to the executable with -Wl,-rpath,'$ORIGIN' in bash or -Wl,-rpath,'$$ORIGIN' in Makefile

note that you need quotes around it to avoid having the shell interpret it as a variable, and if you try to do this in a Makefile, you need $$ to avoid having make interpret the $ as well
