When build the project laplacian from repo app, found the error:

"Generation of 'D:\halide_test\build\CMakeFiles\a1bccc90b3ec1be20a79f7bfe8eeaa42\local_laplacian.update.rule' depends on 'D:\HALIDE_TEST\BUILD\LOCAL_LAPLACIA N.H' generated by 'D:\halide_test \build\CMakeFiles\a3904a6b9ddb43e468c227dc47ef3f5d\local_laplacian.h.rule'.

I build in windows with halide version 17.0.2 and installed halide with vcpkg, is that any installation problem cause this error? I had build my private project and found same error, so I build a sample project of github https://github.com/halide/Halide/tree/main/apps/local_laplacian for checking any building env problem, so please give a hints about this.
