cmake_minimum_required(VERSION 3.4)

# The `cmake_minimum_required(VERSION 3.4...3.18)` syntax does not work with
# some versions of VS that have a patched CMake 3.11. This forces us to emulate
# the behavior using the following workaround:
if(${CMAKE_VERSION} VERSION_LESS 3.18)
  cmake_policy(VERSION ${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION})
else()
  cmake_policy(VERSION 3.18)
