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