EXECUTE_PROCESS() has been around since at least 3.0, and EXEC_PROGRAM()
is deprecated as of 3.28:
CMake Warning (dev) at cmake/cmake_uninstall.cmake:12 (EXEC_PROGRAM):
Policy CMP0153 is not set: The exec_program command should not be called.
Run "cmake --help-policy CMP0153" for policy details. Use the cmake_policy
command to set the policy and suppress this warning.
Use execute_process() instead.
