Compilation for only CPU mode

[kushalvyas]

I want to compile the library for a plain CPU . Installation asks for Opencv_contrib with CUDA support.

Any hack around this ?

Hi kushal,
If go through the code base of OD many of the functions require cuda support and moreover you also need to install opencv along with cudafeatures2d .

Since CUDA is one of the dependancy, so you will be needing:

• A CUDA-capable GPU
  

• A supported version of Microsoft Windows
  

• A supported version of Microsoft Visual Studio
  

• the NVIDIA CUDA Toolkit (available at http://developer.nvidia.com/cuda-downloads)
