法一

编译qt源码
进入源码目录，命令行输入，
./configure.bat -no-warnings-are-errors -xplatform wasm-emscripten -platform win32-g++ -nomake examples -prefix %CD%\qtbase
大概10分钟就可以编译完毕

构建需要的模块
E:/Qt/Qt5.10.1/Tools/mingw530_32/bin/make.exe module-qtbase module-qtdeclarative
如果不需要裁剪，可以直接 E:/Qt/Qt5.10.1/Tools/mingw530_32/bin/make.exe
