8# The CMAKE_EFFECTIVE_SYSTEM_NAME is used to load compiler and compiler
9# wrapper configuration files. By default it equals to CMAKE_SYSTEM_NAME
10# but could be overridden in the ${CMAKE_SYSTEM_NAME}-Initialize files.
11#
12# It is useful to share the same aforementioned configuration files and
13# avoids duplicating them in case of tightly related platforms.
14#
15# An example are the platforms supported by Xcode (macOS, iOS, tvOS,
16# and watchOS). For all of those the CMAKE_EFFECTIVE_SYSTEM_NAME is
17# set to Apple which results in using
18# Platform/Apple-AppleClang-CXX.cmake for the Apple C++ compiler.
