could also be requested at cmake invocation with
---------------------------------------------------
# -D<var>:<type>=<value>: Create a cmake cache entry.
When cmake is first run in an empty build tree, it creates a CMakeCache.txt
file and populates it with customizable settings for the project. This option
may be used to specify a setting that takes priority over the project's default
value. The option may be repeated for as many cache entries as desired.
---------------------------------------------------
There is no way to change a policy from the cache. That is not really
how policies are supposed to work. It is for the developer of the
CmakeLists.txt files to set the policies as they see fit. The -D
options are user options. In most cases, moving to a NEW policy will
require changes to the CMakeLists.txt files so doing it from the command
line would not make sense.
Here is the documentation for polices:
