Do not force CUDA_HOST_COMPILER to g++

cmake sets CUDA_HOST_COMPILER automatically based on CC environment
variable. If one uses custom CC variable and CUDA_HOST_COMPILER is set
this way, build usually fails. This happens, for example, when one
needs to use an older compiler (e.g. gcc-5), because the newer default
compiler is not supported by CUDA.

This fixes #10.
