Hello world Cmake error. The source directory "/work" does not appear to contain CMakeLists.txt.

Following the instructions of the [hello-world tutorial](https://docs.itk.org/projects/wasm/en/latest/cxx/tutorial/hello_world.html). I get the following error:

```
Not searching for unused variables given on the command line.
CMake Error: The source directory "/work" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
ninja: fatal: invalid -j parameter

😵 undefined
```

My system:
- Fedora 42
- Docker 4.37.1
- npm 10.9.2

I am not aware what happens in the Docker images but it doesn't seem to copy the `CMakeLists.txt` into the docker image?

My directory contains when I run the instructions (setup and build):

```
-rw-r--r--. 1 89 Jul 30 11:49 CMakeLists.txt
-rw-r--r--. 1 96 Jul 30 11:56 hello.cxx
