Nomadic Labs is using libusb and hidapi for the Octez project at https://gitlab.com/tezos/tezos written in Ocaml.

Is there a clean way to compile and install both static and shared libraries at the same time?

@pietro submitted an MR to Alpine aports to have both static and shared libraries for package libusb-dev and is now available in Alpine 3.15+:

We did the same for package hidapi-dev but the switch to cmake removed the static libraries from Alpine 3.15 starting with 0.11.0:

At the moment we have no other solutions than building from source or use a custom Alpine package. We copied the current GitHub workflow for Ubuntu and run the configure/build/install twice:

https://gitlab.com/nomadic-labs/hidapi-apk/-/blob/main/APKBUILD#L21

# Shared libraries
cmake -B build/shared -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib -DBUILD_SHARED_LIBS=TRUE
cmake --build build/shared
cmake --install build/shared
# Static libraries
cmake -B build/static -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib -DBUILD_SHARED_LIBS=FALSE
cmake --build build/static
cmake --install build/static

I have no experience with cmake, my concern is that we overwrite the following files instlalling twice:

/usr/lib/cmake/hidapi/hidapi-config-version.cmake
/usr/lib/cmake/hidapi/hidapi-config.cmake
/usr/lib/cmake/hidapi/hidapi-release.cmake
/usr/lib/cmake/hidapi/hidapi.cmake
