Compiler id for Apple Clang is now AppleClang.
|
|
|
|
CMake >= 3.0 recognize that Apple Clang is a different compiler
|
|
than upstream Clang and that they have different version numbers.
|
|
CMake now prefers to present this to projects by setting
|
|
CMAKE_<LANG>_COMPILER_ID to "AppleClang" instead of "Clang". However,
|
|
existing projects may assume the compiler id for Apple Clang is just
|
|
"Clang" as it was in CMake < 3.0. Therefore this policy determines
|
|
for Apple Clang which compiler id to report in
|
|
CMAKE_<LANG>_COMPILER_ID after <LANG> is enabled by the project() or
|
|
enable_language() command.
|
|
|
|
The OLD behavior for this policy is to use compiler id "Clang". The
|
|
NEW behavior for this policy is to use compiler id "AppleClang".
|
|
|
|
This policy was introduced in CMake version 3.0. CMake version
|
|
|release| warns when the policy is not set and uses OLD behavior. Use
|
|
the cmake_policy command to set it to OLD or NEW explicitly.
