Review Comment:
The use of `if (DEFINED SKBUILD_PROJECT_NAME)` could be problematic if
`SKBUILD_PROJECT_NAME` is defined as an empty string. In that scenario,
`tvm_ffi_arg__STUB_PKG` would also become an empty string, which might lead to
unexpected behavior in the stub generation script.
To make this check more robust, I suggest using `if (SKBUILD_PROJECT_NAME)`.
This will evaluate to true only if the variable is defined and contains a
non-empty, non-false value, which is the desired behavior here.
```
if (SKBUILD_PROJECT_NAME)
```
