Apple/M1: compile fails with Bison 3

[edsiper]

When compiling in an environment that contains Bison 3, it fails:

$ cmake -DCMT_DEV=on ../
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.
