CMAKE_<LANG>_COMPILER_EXTERNAL_TOOLCHAIN
----------------------------------------

The external toolchain for cross-compiling, if supported.

Some compiler toolchains do not ship their own auxilliary utilities such as
archivers and linkers.  The compiler driver may support a command-line argument
to specify the location of such tools.  CMAKE_<LANG>_COMPILER_EXTERNAL_TOOLCHAIN
may be set to a path to a path to the external toolchain and will be passed
to the compiler driver if supported.

This variable may only be set in a toolchain file specified by
the :variable:`CMAKE_TOOLCHAIN_FILE` variable.
Allow toolchain files to specify an external toolchain. Clang can compile code, but uses the gcc tools for other tasks such as linking. The -gcc-toolchain option can be used for that, but generalize so that other compilers can be treated the same. If such a location is specified, use it as a hint for finding the binutils executables. 2013-08-08 19:36:36 +04:00			`CMAKE_<LANG>_COMPILER_EXTERNAL_TOOLCHAIN`
