[CMake] specifying path for license file for commercial compiler?

[Stephen McDowell]

I agree that a toolchain file is more appropriate, noting that typically
modifying the environment variables is much more common for there's
compilers (particularly using environment modules).

However, since you've started clearly you would rather not set the
environment variables, there may be an easier "hack".

Intel also looks in /opt/intel/licenses for any .lic files. So if you want,
you can just create a symbolic link or copy your license file there :)
