cmake: Avoid using target_properties for old cmake
CMake versions less than 3.0 do not support the `target_sources`
command. In order to be able to support v2.8.12.2 of cmake, add the
extra targets directly to the target command.
This is a backport from the development branch, except that the uses in
this branch are simpler, and modifying the SOURCES property directly is
not needed.
Fixes #3801
