Yes and no. You can re-configure it, but that'll require deleting and
re-creating the build directory since CMake does not support changing
the Buildtype in an existing build-tree.

You could simply add another build directory in the project
configuration and switch between the two.

A string passed as arguments to the cmake invocation. So anything you
can pass to cmake on the commandline you can put in here too. What I'm
not sure about right now is wether it properly supports spaces in
argument-values or simply does a str.split(" ") to get a list of
arguments from it.

Thats something to look up in the cmake manual or the cmake mailinglist.

If you leave it empty, cmake will choose one - which is /usr/local on
Linux as documented in the cmake manual.
