cmake-gui: Replace command-line install dialog with information box

The QMacInstallDialog infrastructure no longer works on modern OS X
versions.  Drop it and replace the dialog with a simple info box that
explains to the user how to run 'cmake-gui --install' to add symlinks.
Also suggest simply modifying the PATH.

This approach is similar to the Xcode 'xcode-select --install' method
of installing Xcode Command Line Tools.
