QT for webassembly

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

法二

git clone https://github.com/korczis/emscripten-qt
export EMSCRIPTEN_ROOT_PATH=/home/path/to/put/emscripten/emscripten/

mkdir build-emscripten-qt
cd build-emscripten-qt
