As noted previously, upstream doesn't recommend the individual source files. Of course, in Debian we use sources like those that exist in the VCS repository for easy tracking of changes. Upstream even says using / creating an amalgamation is how SQLite3 should be compiled to let the compiler choose the best optimization techniques. That way the execution step can be increased by 5% to 10% [1]. Compilation time however happens only once. Once I already used parallel building and as I remember, not every time but often enough it just broke. Can do testing locally and if someone can help (donate) me old / small architectures - RISC-V for example -, then I plan to re-test parallel compilation.
