Priority: P4: Low
Affects Version/s: 5.9.1
Fix Version/s: None
Component/s: Build tools: windeployqt
Environment:Windows 7 x64
Compiler: mingw-w64 7.1, both i686 and x86_64 (from mingw-builds)
Build options include `-release` and `-force-debug-info`.
When Qt is built in release mode with debug information, windeployqt detects the plugins (e.g. qwindows platform plugin) as debug binaries and refuses to use them.
Specifying `–release` fails because Qt thinks the binaries are not release binaries.
Specifying `–debug` fails because Qt expects the binaries to match `*d.dll`, which they are not because Qt is built in release mode.
Either way, windeployqt complains `Unable to find the platform plugin.` and quits.
It looks like
QTBUG-48976 might have removed a possible workaround option.
