带有MSYS2的Windows x64上的Qt5.6.0 - 未知模块：小部件核心gui

Question

我有一个Qt5项目，我想排除额外的依赖项，如ICU，openssl等，因为这些不需要。

我正在使用MSYS2环境来构建应用程序，因此需要在相同的环境中构建Qt。

构建的最终配置（唯一会导致编译成功的配置）如下所示：

./configure -prefix /usr -no-opengl -no-icu -no-dbus -no-fontconfig \
-no-harfbuzz -no-freetype -no-compile-examples -nomake tests \
-skip qtwebview -skip qtactiveqt -skip qtandroidextras \
-skip qtcanvas3d -skip qtconnectivity -skip qtdeclarative \
-skip qtdoc -skip qtenginio -skip qtlocation -skip qtmacextras \
-skip qtmultimedia -skip qtscript -skip qtsensors -skip qtserialbus \
-skip qtserialport -skip qtsvg -skip qttranslations -skip qtwayland \
-skip qtwebchannel -skip qtwebengine -skip qtwebsockets \
-skip qtwebview -skip qtwinextras -skip qtx11extras \
-skip qtxmlpatterns -skip qttools -platform win32-g++

我使用-prefix /usr将构建的库和二进制文件安装到我的MSYS2中，但在我尝试在项目位置运行qmake后，我收到错误：

Unknown QT modules: widgets gui core

我确认所有需要的DLL都在正确的位置，而且.h都可用，但仍然无法理解为什么qmake毕竟不了解这些模块？

在线搜索类似的错误会产生很多无用的输出..

UPD ：输出config.summary

$ cat config.summary
