Merge #19: Split sources for easier buildsystem integration
Browse files Browse the repository at this point in the history
4a5b0a1 build: Move source entries out to sources.mk (Cory Fields)
6c7d94b build: cleanup wonky gen usage (Cory Fields)

Pull request description:

  This addresses issues like the one in bitcoin/bitcoin#12467, where some of our compiler flags end up being dropped during the subconfigure of Univalue. Specifically, we're still using the compiler-default c++ version rather than forcing c++17.

  We can drop the need subconfigure completely in favor of a tighter build integration, where the sources are listed separately from the build recipes, so that they may be included directly by upstream projects. This is similar to the way leveldb build integration works in Core.

  A similar split was recently added for minisketch: sipa/minisketch#8

  Upstream benefits of this approach include:
  - Better caching (for ex. ccache and autoconf)
  - No need for a slow subconfigure
  - No more missing compile flags
  - Compile only the objects needed

  There are no benefits to Univalue itself that I can think of. These changes should be a no-op here, and to downstreams as well until they take advantage of the new sources.mk. Once merged, [This Core branch](https://github.com/theuni/bitcoin/commits/univalue-split) is ready-ish for PR, and takes advantage of the features added here.

  libsecp256k1 will get the same treatment once this is done.
