# This script is to be used by the ci environment from the project root directory, do not use it from somewhere else.

# Compiles cockatrice inside of a ci environment
# --format runs the clang-format script first
# --install runs make install
# --package [<package type>] runs make package, optionally force the type
# --suffix <suffix> renames package with this suffix, requires arg
# --server compiles servatrice
# --test runs tests
# --debug or --release or <arg> sets the build type ie CMAKE_BUILD_TYPE
# --ccache uses ccache and shows stats
# --dir <dir> sets the name of the build dir, default is "build"
# uses env: BUILDTYPE CHECK_FORMAT MAKE_INSTALL MAKE_PACKAGE PACKAGE_TYPE PACKAGE_SUFFIX MAKE_SERVER MAKE_TEST USE_CCACHE BUILD_DIR (correspond to args: <buildtype>/--debug/--release --format --install --package <package type> --suffix <suffix> --server --test --ccache --dir <dir>)
