[CMake] Errors in Info.plist of Mac GUI app for CMake 2.8.9

[James Walker]

The Info.plist for CMake 2.8-9.app has an empty string for CFBundleName, 
making it show up without a name in utilities such as Activity Monitor. 
  It's also bad that there is an empty string for CFBundleIdentifier, 
CFBundleVersion, CFBundleShortVersionString, CFBundleGetInfoString, and 
NSHumanReadableCopyright.
