Aggregating source files in this way fundamentally collides with the
concept of source file properties, a well-established CMake feature.
Thus, it would require a check if the aggregated source files are to
be compiled with exactly the same flags/definitions/etc. If not, one
would need to trade off aggregation against source file properties,
perhaps by use of a variable/property/policy or whatever solution
might suit. Not that trivial, IMO.
