#64194: portgroup cmake 1.1: add Xcode Generator

-------------------------+--------------------------
 At the moment, there's no way to specify {{{Xcode}}} as a Generator in the
 CMake 1.1 PortGroup. Attempting to specify

 {{{
 cmake.generator Xcode
 }}}

 results in the following error:

 {{{
 Error: Unable to open port: can't set "cmake.generator":
 The "Xcode" generator is not currently known/supported
 (cmake.generator is case-sensitive!)
 }}}

 Using the Xcode Generator causes CMake to generate an Xcode project
 ({{{.xcodeproj}}}) during the configure phase, and seems like it would be
 fairly common use case.

 For the time being, I can tell CMake to use the Xcode Generator by using
 the CMake 1.0 PortGroup, and specifying

 {{{
 configure.args-prepend "-G Xcode"
 }}}
