"""Call this function from the WORKSPACE file to initialize rules_foreign_cc \
dependencies and let neccesary code generation happen \
(Code generation is needed to support different variants of the C++ Starlark API.).
Args:
native_tools_toolchains: pass the toolchains for toolchain types
'@rules_foreign_cc//toolchains:cmake_toolchain' and
'@rules_foreign_cc//toolchains:ninja_toolchain' with the needed platform constraints.
If you do not pass anything, registered default toolchains will be selected (see below).
register_default_tools: If True, the cmake and ninja toolchains, calling corresponding
preinstalled binaries by name (cmake, ninja) will be registered after
'native_tools_toolchains' without any platform constraints. The default is True.
cmake_version: The target version of the cmake toolchain if `register_default_tools`
or `register_built_tools` is set to `True`.
make_version: The target version of the default make toolchain if `register_built_tools`
is set to `True`.
ninja_version: The target version of the ninja toolchain if `register_default_tools`
or `register_built_tools` is set to `True`.
register_preinstalled_tools: If true, toolchains will be registered for the native built tools
installed on the exec host
register_built_tools: If true, toolchains that build the tools from source are registered
additional_shell_toolchain_mappings: Mappings of the shell toolchain functions to
execution and target platforms constraints. Similar to what defined in
@rules_foreign_cc//foreign_cc/private/shell_toolchain/toolchains:toolchain_mappings.bzl
in the TOOLCHAIN_MAPPINGS list. Please refer to example in @rules_foreign_cc//toolchain_examples.
additional_shell_toolchain_package: A package under which additional toolchains, referencing
the generated data for the passed additonal_shell_toolchain_mappings, will be defined.
This value is needed since register_toolchains() is called for these toolchains.
Please refer to example in @rules_foreign_cc//toolchain_examples.
