How about adding a ci which automatic build shared library?

[zemyblue]

Summary

Add a CI which automatic build the shared libraries.

Motivation

The shared libraries are referenced by other project like finschia for building.
we need to compile shared library every commit is added if we want to apply the changes of wasmvm, but it doesn't seems to do that often. So I propose adding CI to automatically build the shared libraries.

The cosmwasm/wasmvm already do auto commit it.

    steps:
      - add_ssh_keys:
          fingerprints:

            # (see https://app.circleci.com/settings/project/github/CosmWasm/wasmvm/ssh and https://github.com/CosmWasm/wasmvm/settings/keys)
            - "31:de:e5:84:1b:12:81:94:aa:06:50:c0:cb:bd:79:f0"
      - checkout
      - run:

          command: make release-build-linux
      - run:
          name: Build shared library for macOS
          command: make release-build-macos
      # Shared libraries for Windows (.dll) currently do not work (https://github.com/CosmWasm/wasmvm/issues/389)
      # and .dll builds are not deterministic.
      # Deactivating this step to avoid polluting the git hostory.

      #     name: Build shared library for Windows
      #     command: make release-build-windows
      - run:

          command: ls -l ./internal/api
      - run:
          name: Configure git user
          # This is not a GitHub user and no permissions can be configured other than "push access", which
          # we can configure for Deploy keys at https://github.com/CosmWasm/wasmvm/settings/keys
          command: |
            git config user.email "wasmvm@circleci.confio.example.com"
            git config user.name "Deployer"
      - run:
          name: Check-in and push new libraries
          command: |
            git status
            git add ./internal/api
            git commit --allow-empty -m '[skip ci] Built release libraries'
            git push origin $CIRCLE_BRANCH

Proposal

• If new commit is added in main branch, a CI automatically detect and add new PR which compile the shared libraries and change it. -> if there is no changed in the shared libraries to build, do not this.
• if the all test of the PR are passed, do auto-merge.
