Both of them build the same source file: `test.cpp`. The only differences are that gen needs a different relative path to the include directories and defines the macro definition: `gen_time`.
This method is setup where all the metaprogram's code are the within the same files as the regular program's code.
If in your use case, you decide to have exclusive separation or partial separation of the metaprogam's code from the program's code files, then your build configuration would need to change to reflect that (specifically the sources).

**The reason:** Its difficult to parse without enough benefits.
Most of the time, the critical complex metaprogramming conundrums are producing the frame of abstractions around the expressions (which this library provides constructors to help validate, you can skip that process by using the untyped constructors).
Its not very much a priority to add such a level of complexity to the library when there isn't a high reward or need for it.
