This ports upb's WORKSPACE scraping logic to protobuf, and allows us to dynamically fetch our dependencies at the exact same pinned version as in Bazel via protobuf_FETCH_DEPENDENCIES=ON. This is mostly for development purposes, and is preferable to git submodules. In a later cl we will flip the default behavior to "package" #test-continuous PiperOrigin-RevId: 686265348pull/18806/head

# upb CMake build (EXPERIMENTAL) |
||||
|
||||
upb's CMake support is experimental. The core library builds successfully |
||||
under CMake, and this is verified by the Bazel tests in this directory. |
||||
However there is no support for building the upb compiler or for generating |
||||
.upb.c/upb.h files. This means upb's CMake support is incomplete at best, |
||||
unless your application is intended to be purely reflective. |
||||
|
||||
If you find this CMake setup useful in its current state, please consider |
||||
filing an issue so we know. If you have suggestions for how it could be |
||||
more useful (and particularly if you can contribute some code for it) |
||||
please feel free to file an issue for that too. Do keep in mind that upb |
||||
does not currently provide any ABI stability, so we want to avoid providing |
||||
a shared library. |
||||
|
||||
The CMakeLists.txt is generated from the Bazel BUILD files using the Python |
||||
scripts in this directory. We want to avoid having two separate sources of |
||||
truth that both need to be updated when a file is added or removed. |
||||
|
||||
This directory also contains some generated files that would be created |
||||
on the fly during a Bazel build. These are automatically kept in sync by |
||||
the Bazel test `//cmake:test_generated_files`. |
