As there is no example in the documentaion,
could someone clarify me if the change of any policy
that should require an additional
cmake_policy(SET CMP<NNNN> NEW)
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.
---------------------------------------------------
Regards
Marco
