[bug#31531] [PATCH 2/3] gnu: monero: Update to 0.12.0.0.

[Ricardo Wurmus]

Hi Theodoros,

> * gnu/packages/patches/monero-fix-version.patch: New file.
> * gnu/local.mk: Add it.

I think that this patch is better implemented using “substitute*” in a
build phase.

> * gnu/packages/finance.scm: Update to 0.12.0.0.
> [source]: Add patch.
> [inputs]: Add zeromq, cppzmq, libsodium.
> [arguments]: Change build-type to "release".
> Add argument on unit-tests phase.
> Substitute system* with invoke.

The last step (using “invoke”) is better done in a separate patch.

Wha does the TODO comment mean?

> + function (write_static_version_header hash)
> +   set(VERSIONTAG "${hash}")
> +-  configure_file("src/version.cpp.in" "version.cpp")
> ++  configure_file("${CMAKE_SOURCE_DIR}/src/version.cpp.in" 
> "${CMAKE_BINARY_DIR}/version.cpp")
> + endfunction ()

I’d prefer this to be a short substitute* snippet instead of a patch file.
