This PR is a blocker for CGAL-6.0-beta1, because it impacts downstream packages.

I have checked with cmake versions 3.12, 3.18, 3.19, and 3.29 (thanks to Fedora toolbox and a setup script).

That does not work with cmake-3.11, and I do not really understand why.

With cmake -DWITH_tests=ON, the error is:

-- Configuring test in test/Installation
CMake Warning (dev) at Installation/cmake/modules/CGAL_add_test.cmake:176 (if):
  Policy CMP0064 is not set: Support new TEST if() operator.  Run "cmake
  --help-policy CMP0064" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  TEST will be interpreted as an operator when the policy is set to NEW.
  Since the policy is not set the OLD behavior will be used.
