> I do have opinions, but before I give any, is my understanding of all this correct? Yes, exactly.. IMO this saves time of configuration.. Furthermore, in addition to it doesn't requires user to set .bashrc (only if the user want), it also avoids an other problem: Suppose that I moved my repo to other folder.. In the current state, I would have to change again these variables in .bashcrc.. Otherwise, the code will continue generating binaries to the old folder.. With the process proposed to me, it's occurs in an automatic way, without need user intervention..
