You will always depend on other libraries like libpng etc. so, no,
compile a C++ program, and hope to be ale to run it on "all linux
version" (even assuming it's the same target architecture).

I don't think this is missing as it is neither wanted, nor needed.
The SDK is meant as a way to get a quick start as an individual
programmer. It is not meant as a replacement for proper packaging
for things you create locally.

It's not a requirement.

I don't know. I am seeing the message myself, but did not take the
to track down the reason so far. Seems to be in the "Mostly Harmless"
category anyway, and more of a Qt issue, than a Qt Creator one.

Or install the compile dependencies, like X development packages.

Software distribution on Linux usually happens as source, or as proper
packages for the target system's packaging system. Distributing
"standalone" binaries is rather uncommon, and usually only done when
you don't have the resources to build "native" packages, or want
to provide something pre-compiled quicker than the distributions.

I am afraid I don't understand this one.
A Linux ISO? A bootable "Qt SDK"?
