[cmake-developers] use-correct-rcc-command-option topic

[Brad King]

Steve,

In regard to:

 Revert "cmQtAutoGenerators: Fix rcc invocation for Qt 5.0 and 5.1 (#15644)"
 https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=08147a9a

The proper fix is to detect whether rcc supports --list or -list and user
the preferred one based on the version available, not to revert to the
broken state.  I will not merge the topic as-is.
