Qt create static library for all architectures

[range36rus]

Hello. I try build static library for Android (*.a). My pro-file:

QT -= gui

TEMPLATE = lib
CONFIG += staticlib

CONFIG += c++11

DEFINES += QT_DEPRECATED_WARNINGS

ANDROID_ABIS = armeabi-v7a arm64-v8a x86 x86_64

SOURCES += \
    untitled3.cpp

HEADERS += \
    untitled3.h

Files untitled3.cpp and untitled3.h very simple. When I build project I get the only one library *.a, but expected get four libs for all architectures: armeabi-v7a arm64-v8a x86 x86_64

When I build at first, compilation finished with error:

Error while building/deploying project untitled3 (kit: Android for armeabi-v7a,arm64-v8a,x86,x86_64 (Clang Qt 5.14.1 for Android))
When executing step "Make"
10:13:58: Elapsed time: 00:01.

When I build at second, compilation finished successfully, but in output dir I find one *.a - lib:

In folders armeabi-v7a arm64-v8a x86 x86_64 exist only *.obj - files, but not exist .a - files.
My question: how correct build static library (.a) for android for all (4) architectures?
P.S.: Qt version for Android: 5.14.1; Qt Creator version: 4.11.0, based on Qt version: 5.14.0
