-# Workaround issue with creating symbolic links due to issues with native
-# path conversion (TO_NATIVE_PATH). The following summarizes what CMake invocations
-# this workaround is for:
-#
-# 1. CMake from command line + Ninja = No errors
-# 2. CMake from command line + MinGW Makefiles = Forward slash for paths, mklink mistakes path for a switch
-# 3. CMake from MSYS + Ninja = No errors
-# 4. CMake from MSYS + Unix Makefiles/MSYS Makefiles = Forward slash for paths, mklink mistakes path for a switch
-#
-# There are references to the issue in case (2) and (4) in https://github.com/ARMmbed/mbedtls/issues/1496,
-# https://cmake.org/pipermail/cmake/2006-July/010193.html, and https://cmake.org/Bug/view.php?id=5939.
