Support Trilinos-based Kokkos installation.

The follow changes to CMakeLists.txt will support a shared library build of Compose, linking against Kokkos inside of Trilinos built with shared libraries. I use the CMake variable "KOKKOS_IN_TRILINOS," but obviously this can be changed to whatever you would like.

Also, this has not been tested on a static library build, or against Trilinos built as static libraries.

PR #19 permits installation as a shared library. Trilinos-based Kokkos support will be a separate PR.
