Any way to set the ENV enviroment variables during compilation?

**Version of emscripten/emsdk:**
3.1.54

Hi, may I enquire if there is any way to set the environment variables during compilation? I do see the way to set the environments in JavaScript code here https://emscripten.org/docs/porting/connecting_cpp_and_javascript/Interacting-with-code.html#environment-variables, but I'm just curious if it could be set up during compilation. I tried to use `set_property` in CMake but it seems can't work.

Thank you very much!
