_ZNSt18condition_variable4waitERSt1unique_lockStmutexE could not be located in the dynamic link library path QT5Core.dll.
Often, this means you accidentally deployed the MSVC version instead of the MinGW version of Qt5Core.dll.
The recommended way to deploy is to use windeployqt.
If you want to deploy manually, make sure you copy the correct DLLs (do not take any DLLs from the Qt Creator folder!) See http://wiki.qt.io/Deploy_an_Application_on_Windows for details.
