How to change the default path gnuplot searches when changing terminal type?

I am a user of a HPC system. I now would like to install a new version of gnuplot under my directory /home/username. I succeeded in installing, but now the default terminal type is qt. I now want to change it to x11. The command set terminal x11 is not working, the error messages are:

Expected X11 driver: /home/app/gnuplot-5.0.6/libexec/gnuplot/5.0/gnuplot_x11 Exec failed: No such file or directory See 'help x11' for more details

This is weird as I installed the gnuplot in

/home/username/app/gnuplot-5.0.6/

and there is a gnuplot_x11 in

/home/username/app/gnuplot-5.0.6/libexec/gnuplot/5.0/gnuplot_x11

Is there a way to tell gnuplot that it searches in the wrong path? And is there a way to set the x11 terminal as the default one?

Thank you very much!

Update:

I can set --with-qt=no, now the default becomes wxt. Now I can use set terminal x11: 

gnuplot> set terminal x11
Terminal type set to 'x11'
Options are ' nopersist enhanced'

I am not quite understand why.

You can change the directory in which gnuplot looks for the gnuplot_x11 driver by setting the GNUPLOT_DRIVER_DIR environment variable. From help x11:

The gnuplot outboard driver, gnuplot_x11, is searched in a default place chosen when the program is compiled. You can override that by defining the environment variable GNUPLOT_DRIVER_DIR to point to a different location.
