C plotting library GR not working

Question

I am trying to install C library GR [Link] on Ubuntu 18.04, after following the instructions to install, there is no error while installing but when using it gives the error :

foo.c:2:10: fatal error: gr.h: No such file or directory #include ^~~~~~ compilation terminated.

This is while compiling the example given on their installation page.

Is the installation faulty? Can anyone help me regarding this?

Thank You in advance.

Please improve the question: are you trying to compile the sample from the installation page or it's your project? — AndrewQ, Mar 24 '19 at 23:00
The C compiler does not find the "gr.h" header file. 1) Check if the file exists and if you can access it. 2) Try to modify the example in: #include "path_to_gr.h/gr.h" — AndrewQ, Mar 25 '19 at 10:48

By specifying location of GR through addition flags the compilation is possible.
Assuming GR is installed in /usr/local/gr.
The command to run foo.c should be :

gcc -I/usr/local/gr/include foo.c -L/usr/local/gr/lib -lGR -Wl,-rpath,/usr/local/gr/lib
