[sajjadarashhh]

cmake,ninja,emscripten are configured just like everything that i understand from this document

Did you run emsdk_env.bat, or set EMSDK manually?

[sajjadarashhh]

Yes i set that manually

[yowl]

Try using the script, emsdk_env.bat . It will set EMSDK with forward slashes

EMSDK=C:/github/emsdk
