[cmake] Include more link libraries

[FireBurn]

This is required to get dev-libs/rocm-opencl-driver-2.7.0 compiling for me on Gentoo

I think it might be related to using -Wl,--as-needed in my link flags globally

[FireBurn]

Without this patch I see the following errors during compilation:

LGTM.
Btw, LLVM became c++14 a few weks ago, so use -std=c++14 now.

[candrews]

FWIW, LGTM as well. Thank you @FireBurn!
