I can do
   win32-msvc2015 { Do stuff... }
but not
   win32-msvc2017 { Do stuff... }

The only way I see to tell that it's 2017 is to check if it isn't any other 
MS compiler that I use.  Perhaps it's silly, but I try to maintain 
compatibility with 2013, 2015 and 2017 and Qt back to 5.9x.

I use some 3rd party libraries that are built separately and it seems 
safest to use libraries built with a matching compiler.  Less important, I 
include compiler version in my About screen and use DEFINES to get that 
info into the code.

Re: [Qt-creator] CONFIG variables not as expected

Hi Bob,


I'm using Qt 5.14.0 and the bundled Creator 4.11.0 under Windows 7.
In a new or previously existing project using qmake, I display the contents
of CONFIG by message($$CONFIG) in the .pro file.

For a msvc3015 project, I see win32-msvc2015 in the list values.

For a msvc2017 project, I do not see win32-msvc2017 or anything similar.

For a gcc project, I do not see debug_and_release like I do with msvc
projects.


That's probably the outcome from QTBUG-78445, which resulted in QTBUG-80792

There is work ongoing to *allow* separate Qt debug builds again, but the
official release will (most likely) only contain release DLLs with
separate debug information.

I'm actually doing the other way round, as I'm always shadow-building,
so the additional only complicate things.

Why?
