Can't figure out how to install a C++ library (GLUI) on linux Mint

Question

I have been trying forever to install this: https://github.com/libglui/glui on my Linux mint distribution. I usually install stuff with the command line, and am a novice at manually installing libraries. Basically, I download the Github repo, ran the make file, and was not sure where to go from there. They don't really provide any instructions that I can find.

Basically I ran make and it generated a .a file. I moved this .a file into my /usr/lib/x86_64-linux-gnu folder. Now when I run this:

g++ -o test test.cpp /usr/lib/x86_64-linux-gnu/libOpenCL.so -lGL -lGLU -lglut -lglui -lm -fopenmp

instead of getting my previous error (/usr/bin/ld cannot find -lgui) I get this wall of doom:

/usr/bin/ld: /tmp/ccvdD4zb.o: in function `InitGlui()':
sample.cpp:(.text+0x10d4): undefined reference to `GLUI_Master_Object::create_glui(char*, long, int, int)'

collect2: error: ld returned 1 exit status

Obviously I need to do something else with that repo I downloaded and ran the make file for, I just have no idea what and can't seem to find an answer anywhere, please help!

If you look at the project history, commit 936b3d7e6a42c6eab0eecc191861b0a98fa7fc30 (30 Jun 2017) replaced all the mentioned functions with functions that take a const GLUI_String&.

You have apparently picked up a glui.h file somewhere that references the old interface. You should instead copy the glui.h file from the repo to /usr/local/include/GL/glui.h and add -I/usr/local/include to your compile flags. That will make sure the header matching the library is selected and you do not get these errors.
