The quiche+boring CI builds fail on Zuul

[bagder]

I did this

I checked recent CI builds. I noticed that both builds on zuul that build quiche (+boringssl) fail consistently. The build ends with:

  -- Build files have been written to: /home/zuul/quiche/target/release/build/quiche-986e736b297204f2/out/build
  running: "cmake" "--build" "." "--target" "bssl" "--config" "RelWithDebInfo" "--parallel" "8"

  --- stderr
  Unknown argument --parallel
  Unknown argument 8
  Usage: cmake --build <dir> [options] [-- [native-options]]
  Options:
    <dir>          = Project binary directory to be built.
    --target <tgt> = Build <tgt> instead of default targets.
                     May only be specified once.
    --config <cfg> = For multi-configuration tools, choose <cfg>.
    --clean-first  = Build target 'clean' first, then build.
                     (To clean only, use --target 'clean'.)
    --use-stderr   = Ignored.  Behavior is default in CMake >= 3.0.
    --             = Pass remaining options to the native tool.

example failure

I think this is the boringssl part? It looks like it uses a cmake option that the cmake version used here doesn't support.

I expected the following

All quiche builds to be fine.

curl/libcurl version

current git master

operating system

These builds run on ubuntu-bionic.

@ghedo can you make sense of this? Is this the boringssl build from within quiche and if so, do you know if we can make it not use the --parallel option?

[bagder]

Ubuntu bionic ships with cmake 3.10

The cmake --parallel command line option was introduced in cmake 3.12.

... yet the boringssl CMakeLists.txt file says:

cmake_minimum_required(VERSION 3.5)
