Enabling the option --enable-cuda-sdk results in a build failure. Failing component is scale_cuda

[Dennis E. Mungai]

Summary of the bug:

As stated, enabling the option --enable-cuda-sdk results in a build error, as shown below.

How to reproduce:

Having installed all dependencies, including the nv-codec-headers, results in:
