Hi,
So right now I'm trying to go the splitting in two packages way, similar
to what is done for python-cryptography.
So I managed to build the first one that produces a header file in the
store /gnu/store/*/lib/header.h
In the second package, I don't get how to copy this file inside the
build. I've been trying something like this:
```
(native-inputs (list python-fwdpy11-rust-lib))
(arguments
(list
#:phases
#~(modify-phases %standard-phases
(add-before 'build 'copy-rust-lib
(lambda* (#:key native-inputs #:allow-other-keys)
(copy-file (search-input-file
native-inputs "lib/fp11rust_api.h")
"lib/core/internal/fp11rust_api.h"))))))
```
Which complains there is no match, because it seams the package store
path is not present in the native-inputs, although I specify it in the
package.
Thanks,
Alexis

Fair enough, I just meant that it's pretty hard as a newcomer to know
which build system You're supposed to use to start with when
encountering a project where several languages are used.

I'm not sure why this is counter-intuitive. The existence of any rust at
all means you need to build rust code. The normal way to do that in Guix
is to use the cargo-build-system.
Equally, I don't find it strange that the upstream build instructions[1]
ask me to install a rust compiler and cbindgen. I need to do that if I
want to build rust code.
It's also worth noting that there are 22 packages in Cargo.lock[2], so
building the one rust file in the repository is a bit more involved.
