cmake: Fix added sources to targets

Browse Source 
In cmake version < 3.0, the SOURCES property on targets cannot be
modified after the target is defined.  There are several instances in
the code that were using `target_properties()`, which is not available
in the older versions of cmake.  Unfortunately, the workaround in #3801
(381c1078fc) assumes that this SOURCES property can be modified.

Work around this by building up any necessary sources before declaring
the target.  This is more awkward, but needed to continue to be able to
support the old versions of cmake.

Fixes #3788.
