Ошибка импорта при попытке использовать скомпилированный код OpenCV CUDA в Python

Question

Я недавно добавил функциональность CUDA в программу OpenCV C ++.Перед добавлением CUDA я смог скомпилировать код и импортировать его в Python 3.5 через оболочку.Теперь это вызывает ошибку:

ImportError: /path/pythonBindings.so: undefined symbol: _ZN2cv4cuda8subtractERKNS_11_InputArrayES3_RKNS_12_OutputArrayES3_iRNS0_6StreamE

Я могу что-то вроде читать "cuda subtract", функцию, которую я использую один раз в коде.Комментирование этого ничего не делает, хотя я предполагаю, что что-то о CUDA может отсутствовать в файле CMake, может быть ..?Код C ++ работает отлично.Это make-файл и цель:

CXX = g++
CXXFLAGS = -lm -g -Wall -std=c++11 -pthread

OPENCV_INCLUDES = $$(pkg-config opencv --cflags --libs)

TEST_LIBS = -lcppunit

CURRENT_DIR = $(shell pwd)

all:
    $(CXX) $(CXXFLAGS) main.cpp -o main.out $(OPENCV_INCLUDES)

Это цель, которую я использую для привязок python:

python:
    bash -c "rm -rf python-bindings/build"
    bash -c "mkdir python-bindings/build"
    cd python-bindings/build; bash -c "cmake .."
    $(MAKE) -C "python-bindings/build"
    bash -c "cp python-bindings/build/py*.so pythonBindings.so"

И это соответствующий CMakeLists.txt:
