Export cmake config file (#289)

Create and install proper CMake *-target.cmake and *-config.cmake files,
for use by other CMake-using projects.

It installs a file called automotive-dlt-targets.cmake into a common
location for such files, namely
<prefix>/lib/cmake/automotive-dlt/automotive-dlt-targets.cmake
They can now call find_package(automotive-dlt) and obtain a target
called Genivi::dlt that they can link against with target_link_libraries(),
by which they automatically gain all necessary attributes, including libdlt's
include directories.
