QT5.15.2的32bit MinGW静态编译库，编译命令“configure.bat -static -release -confirm-license -opensource -opengl desktop -platform win32-g++ -prefix "D:\Qt\5.15.2\mingw81_32_static" -sql-sqlite -sql-odbc -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -make libs -nomake tools -nomake examples -nomake tests -skip qt3d -skip qtcanvas3d -skip qtdatavis3d -skip qtlocation -skip qtwayland -skip qtwebchannel -skip qtwebengine -skip qtwebsockets -skip qtwebview”，忽略了一些不常用的库，小的程序基本没问题。
