Where to set DevIL

[mahmoodn]

At the end of build I see some messages related to DevIl

[100%] Linking CXX executable ../bin/optixPathTracer
/usr/bin/x86_64-linux-gnu-ld: /home/mahmood/Optix-PathTracer/src/support/DevIL/lib/x64/Release/DevIL.lib(DevIL.dll): Recognised but unhandled machine type (0x8664) in Import Library Format archive

I didn't find any variable for DevIL. I have that but don't know how to tell Optix-PathTracer.

I haven't tested this on Linux but maybe you might need to try with a fresh installation of DevIL as merlinND mentioned in this PR #7

What is the difference between using and not using DevIL then? Is it mandatory?
