Fix: change libts to export a CMake package

libts install content was not compatible to find_module() which made
using a pre-built libts binary from CMake less than ideal.

This change adds the missing files and updates export and install
commands to make libts generate a proper CMake package.

From now on an external project will be able to use find_module() to
integrate libts into its build.
