MATLAB: Does packNgo throw a warning when external CUDA files are included in the generated code

GPU Coder

I am trying to relocate my generated CUDA code to another environment. In that environment, I received an error about a missing header file "cublas_v2.h".
So I tried to use packNgo to make sure that I have all dependencies packaged into an archive. However, I get the following warning that packNgo cannot find the external CUDA files:
cfg = coder.gpuConfig('dll');
codegen -config cfg My_Function;
cd codegen/dll/My_Function;
load buildInfo.mat
packNGo(buildInfo,'packType', 'flat', 'fileName','portMy_Function');
Warning: The following error occurred while attempting to run the preprocessor
to find the minimum needed set of include files:
While parsing the source file '...\codegen\dll\My_Function\My_Function_data.cu'
the following error occurred:
...\codegen\dll\My_Function\My_Function_types.h:31:
cannot open source file "cublas_v2.h"
| #include "cublas_v2.h"
|            ^

This is a known limitation. PackNGo is supported with GPU Coder only with 'MinimalHeaders' set to false.

See the following documentation page for more information:

Hint: the external CUDA files can be found at the following location:

$matlabroot$\sys\cuda\win64\cuda\include
