Andy Green 53d195022f cmake: Enable WITH_MINIMAL_EXAMPLES by default 
Although many of the examples must be run from the example directory as
cwd, everyone getting started probably wants to try the examples, cmake
knows how to do it, so let's enable it by default.

You can also test the client Basic Auth support against the http-server/minimal-http-server-basicauth example. In one console window run the server and in the other

$ lws-minimal-http-client -l --nossl --path /secret/index.html --user user --password password

The Basic Auth credentials for the test server are literally username "user" and password "password".
