Update html when setting EXPORT_NAME

Hello,
I would like to set `EXPORT_NAME` in my webassembly project.
I do the following with cmake:

```
target_link_libraries(MyProjectWebAssembly PRIVATE "-s MODULARIZE=1 -s EXPORT_NAME=ModuleForMyProject")
```

When I compile, I get the following error:

```
em++: error: Customizing EXPORT_NAME requires that the HTML be customized to use that name (see https://github.com/emscripten-core/emscripten/issues/10086)
my_library\CMakeFiles\MyProjectWebAssembly.dir\build.make:99: recipe for target 'bin/MyProjectWebAssembly.html' failed
mingw32-make[2]: *** [bin/MyProjectWebAssembly.html] Error 1
```

What do I need to update in my html file?
```

MyProject Webassembly


function f() {
Module['callMain']();
}
setTimeout(f, 1000);

```

Thank you!
