-# XXX Emscripten:
-# This file is copied as-is from the CMake source tree. Due to how CMake
-# platform toolchain files work, we must have a copy of this file located
-# relative to Emscripten platform toolchain file, or file inclusion order
-# in cmGlobalGenerator::EnableLanguage will not find Emscripten.cmake
-# toolchain file, and as a result, it is not possible to set the default
-# compilation output suffix to .js, and as a consequence the script
-# check_function_exists() will not function properly (it will try to
-# build to wrong file suffix)
