How to disable adding 'd' suffix to debug library name, when building qt?
When you build a debug version of the libraries Qt, to their names suffixed d.
Just my opinion, but I think you have to ask Microsoft on that, since Qt is just following an ages old Microsoft standard of appending a 'd' to their debug DLLs. (And Apple is doing more or less the same, by appending '-debug')
If you don't want your Qt builds to exhibit this behavior, you can switch to Linux, eg. Ubuntu or Debian. In those OS'es no 'd' or '-debug' are suffixed.
Very informative, you do not accidentally teacher of history (sarcasm).
Well, if it is serious then this functionality is hampered, I use a build system that uses switching directories for different platforms and debug and release version.
