CI fails due to cmake failure

[Jasperav]

I recently updated my fork of this and now my CI fails with this error:

  running: "cmake" "/home/runner/.cargo/git/checkouts/prost-0f318a28dfb453a6/2c9d9c1/prost-build/third-party/protobuf/cmake" "-DCMAKE_INSTALL_PREFIX=/home/runner/work/xx/xx/server/target/debug/build/prost-build-744ea9bdfe2d1c67/out" "-DCMAKE_C_FLAGS= -ffunction-sections -fdata-sections -fPIC -m64" "-DCMAKE_C_COMPILER=/usr/bin/cc" "-DCMAKE_CXX_FLAGS= -ffunction-sections -fdata-sections -fPIC -m64" "-DCMAKE_CXX_COMPILER=/usr/bin/c++" "-DCMAKE_ASM_FLAGS= -ffunction-sections -fdata-sections -fPIC -m64" "-DCMAKE_ASM_COMPILER=/usr/bin/cc" "-DCMAKE_BUILD_TYPE=Debug"

  --- stderr
  CMake Error: The source directory "/home/runner/.cargo/git/checkouts/prost-0f318a28dfb453a6/2c9d9c1/prost-build/third-party/protobuf/cmake" does not exist.

How can I fix this?

@Jasperav can you post the version of prost-build you are using?

[Jasperav]

@LucioFranco 10.1, the fork can be found here: https://github.com/Jasperav/prost/blob/master/prost-build/Cargo.toml. I made a few changes in the code, but not something that should directly hit the CI (although I did add another test, but other tests like clippy are also failing)

[LucioFranco]

The fork is missing the git submodule of the protobuf repo. https://github.com/Jasperav/prost/tree/master/prost-build/third-party check this folder on the master branch of this repo.

@LucioFranco Thanks for the reply, I got it working now!
