* Disable debug-and-release builds for MinGWSimon Hausmann2019-09-181-1/+1
| | | | | | | | | | | | | | | | | | | | | The requirement to separate debug and release DLLs on Windows stems from the Visual Studio C run-time library appearing in two different variants (debug and release) and not mixing well. It's possible to perform builds without optimzations and with debug symbols while linking against the release version of the C run-time, but at the same time the debug version of the run-time brings other developer visible advantages. MinGW on the other hand does not have this distinction, does not ship with separate DLLS and does also not require the VS C runtime library. Therefore we do not need this separation for MinGW, which means that our packages can be reduced in size and application developers wishing to debug their applications do not have to use debug builds of the Qt libraries or run into Qt internal debug code.

* Fix builds with some MinGW distributionsKai Koehne2018-08-021-1/+1
| | | | | | | | | | | | | | | | | | | | Some distributions do not define MINGW_HAS_SECURE_API globally, resulting in methods like wgetenv_s not being declared in the headers. This is probably to keep compatibility with Windows XP. Anyhow, we don't support Windows XP anymore, so we can safely add the define. Note that this is not necessary for the mingw-builds distro, which is the only one we test and support. Anyhow, I don't see any risk in adding these for other distributions.
