[Solved] Problems finding libGL.so after install of amdgpu-pro package

I have installed the amdgpu-pro package available at the Arch Linux CN repository here:

https://github.com/archlinuxcn/repo

Now, I am trying to debug an issue where any program that I try to build that requires OpenGL is not able to find it. The package has installed it here:

60> ls /opt/amdgpu-pro/lib/x86_64-linux-gnu/libGL.*
/opt/amdgpu-pro/lib/x86_64-linux-gnu/libGL.so@  /opt/amdgpu-pro/lib/x86_64-linux-gnu/libGL.so.1@  /opt/amdgpu-pro/lib/x86_64-linux-gnu/libGL.so.1.2

And, it added a file in /etc/ld.so.conf.d:

61> cat /etc/ld.so.conf.d/amdgpu-pro.conf 
/opt/amdgpu-pro/lib/x86_64-linux-gnu/

Even ldconfig claims it is in the cache:

63> ldconfig -p | grep libGL.so
	libGL.so.1 (libc6,x86-64) => /opt/amdgpu-pro/lib/x86_64-linux-gnu/libGL.so.1
	libGL.so.1 (libc6) => /opt/amdgpu-pro/lib/i386-linux-gnu/libGL.so.1
	libGL.so (libc6,x86-64) => /opt/amdgpu-pro/lib/x86_64-linux-gnu/libGL.so
	libGL.so (libc6) => /opt/amdgpu-pro/lib/i386-linux-gnu/libGL.so

However, any attempt at compiling a program with this library fails and states that it cannot be found:

19> g++ `sdl2-config --cflags --libs` -lGL -lGLU -o shader_compiler shader_compiler.cpp
/bin/ld: cannot find -lGL

It doesn't even work when I set the LD_LIBRARY_PATH:

20> LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/amdgpu-pro/lib/x86_64-linux-gnu/ g++ `sdl2-config --cflags --libs` -lGL -lGLU -o shader_compiler shader_compiler.cpp
/bin/ld: cannot find -lGL

What can I do to debug this problem further?

Re: [Solved] Problems finding libGL.so after install of amdgpu-pro package

I realized that I was confusing the loader and the linker. When I set the LIBRARY_PATH=/opt/amdgpu-pro/lib/x86_64-linux-gnu, then I am able to build programs and AUR packages which rely on OpenGL.
