How to build osgemscripten example

1. Install Emscripten

Download and install Emscripten portable SDK

2. Create build directory

Run the following commands:

mkdir /path/to/build/dir

cd /path/to/build/dir

3. Configure example

Run the following command:

cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/emsdk-portable/emscripten/<version>/cmake/Modules/Platform/Emscripten.cmake /path/to/OpenSceneGraph/examples/osgemscripten

This also configures OpenSceneGraph as a dependency
