Cleanup the cmake output

[mithro]

Currently cmake complains heavily during the build, figure out what needs to be done to fix the issues;

CMake Warning (dev) at /usr/local/share/cmake-3.19/Modules/ExternalProject.cmake:2143 (message):
  Policy CMP0114 is not set: ExternalProject step targets fully adopt their
  steps.  Run "cmake --help-policy CMP0114" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  ExternalProject target 'antlr4_runtime' would depend on the targets for
  step(s) 'build_static' under policy CMP0114, but this is being left out for
  compatibility since the policy is not set.
Call Stack (most recent call first):

This warning is for project developers.  Use -Wno-dev to suppress it.
