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, directly
set the SOURCES property instead of using the target_sources command.

A future patch could reverse this, if the project decides to forgo
support for cmake versions less than 3.0.

Fixes #3801
