# 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.
#
# This workaround is meant to circumvent logic inside link_to_source() function in mbedtls/mbedtls/CMakeLists.txt.

# using a 'hybrid' path format resilient intermediary - in this case a Python wrapper for mklink. This is more unweildy
