The cmake-policies\(7\) manual explains that the OLD behaviors of all policies are deprecated and that a policy should be set to OLD only under specific short-term circumstances. Projects should be ported to the NEW behavior and not rely on setting a policy to OLD. Call Stack \(most recent call first\): CMakeLists.txt:[0-9]+ \(include\)$
