Description
Starting with qt 5.15.1 the compilation fails with

qwindowsservices.cpp: In function 'bool shellExecute(const QUrl&)':
qwindowsservices.cpp:81:45: error: 'create' is not a member of 'QThread'
81 | QScopedPointer<QThread> thread(QThread::create([path, resultPtr]
|
this seems to be a regression introduced by 45d340851d5f88fb27fb7be011079fa1ae238a3f which adds
QScopedPointer<QThread> thread(QThread::create([path, resultPtr]
() { *resultPtr = runShellExecute(path); }));
but QThread::create is unavailable as it is defined as:
#ifdef Q_CLANG_QDOC
template <typename Function, typename... Args>
static QThread *create(Function &&f, Args &&... args);
template <typename Function>
static QThread *create(Function &&f);
#else
# if QT_CONFIG(cxx11_future)
# ifdef QTHREAD_HAS_VARIADIC_CREATE
template <typename Function, typename... Args>
static QThread *create(Function &&f, Args &&... args);
# else
template <typename Function>
static QThread *create(Function &&f);
# endif // QTHREAD_HAS_VARIADIC_CREATE
# endif // QT_CONFIG(cxx11_future)
#endif // Q_CLANG_QDOC
and cxx11_future does not seems to be present for this compiler
