[Qt-creator] Linux SDK containing Qt Creator doesn't build projects out of the box

[David Ching]

Hello,

I am a Windows developer just getting started with Linux.  This link tells 
of multiple packages which must be installed on Ubuntu before Qt Creator 
will successfully link:

As a Windows developer, I expect the Qt SDK to include everything needed, 
and it does on Windows, but apparently not on Linux?  Why is that?  Because 
not only do I have this problem with Qt Creator, but also my own Qt app 
might have the same distribution issues.  Do I have to redist all of these 
system libraries?  How do app developers support multiple Linux distros 
anyway (e.g. how does the app run on both Ubuntu and Red Hat?).  Any 
pointers to deployment tutorials of Linux software would be greatly 
appreciated.

Thanks,
David
