Harmonise configuration defaults (#937)
* Ensure all options start off for cmake too * Attempt to make the build time config logic in the cmake process match the makefile process * Add a simple muscle memory helper for cmake * Ask them what they are smoking, then tell them to put it out * Avoid occasional stale package cache errors

## CMake configuration

There are still some autodetected libraries in parts of the CMake build
|

system.

There are a number of OPTION statements in the CMakeLists.txt file that can
|
||||
have their settings changed.
|
||||
have their settings changed. This is done by adding a commandline option
|
||||
to the cmake configure stage.
|
||||
|
||||
e.g:
|
||||
`cmake -DN2N_OPTION_USE_ZSTD=ON ..`
|
||||
|
||||
Note that the names of the configure option variables used in the cmake
|
||||
process will probably change to make the source code consistent.
