""" 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//tools/build_defs:cmake_toolchain' and
'@rules_foreign_cc//tools/build_defs: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.
additonal_shell_toolchain_mappings: mappings of the shell toolchain functions to
execution and target platforms constraints. Similar to what defined in
@rules_foreign_cc//tools/build_defs/shell_toolchain/toolchains:toolchain_mappings.bzl
in the TOOLCHAIN_MAPPINGS list.
Please refer to example in @rules_foreign_cc//toolchain_examples.
additonal_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.
