Hi, there is no generic answer to that question. If your build system supports --prefix, it's not too hard to include the prefix in the hard coded path. For a Debian package, that's all you need: a compile-time option. If you want your build to be relocatable (i.e. install path is not known at compile time) you can also make the path relative to the executable binary path. Finally, your program can accept a command line option or an environment variable so the user can set the path. Or even an option in a file the user directory or in /etc. If you implement several of those possibilities, you should make the priority in that order: command-line, environment, user file, /etc file, hard coded value.
