 Emsdk must be activated before it can be used. You can use `activateEmsdkStep` to create a build step for that:
 ```zig
-    const activate_emsdk_step = @import("zemscripten").activateEmsdkStep(b);

+    const activate_emsdk_step = @import("zemscripten").activateEmsdkStep(b, emsdk_dep);
 ```
 
 Add zemscripten's "root" module to your wasm compile target., then create an `emcc` build step. We use zemscripten's default flags and settings which can be overridden for your project specific requirements. Refer to the [emcc documentation](https://emscripten.org/docs/tools_reference/emcc.html). Example build.zig code:
