OpenCV Blender causes CL_BUILD_PROGRAM_FAILURE Just before today, the MultiBandBlender I used runs as expected. Without

Here's my cmake command:

cmake -D CMAKE_BUILD_TYPE=DEBUG\
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D INSTALL_C_EXAMPLES=OFF \
-D CUDA_ARCH_BIN="6.1" \
-D WITH_TBB=ON \
-D WITH_CUDA=ON \
-D BUILD_opencv_cudacodec=OFF \
-D ENABLE_FAST_MATH=1 \
-D CUDA_FAST_MATH=1 \
-D WITH_CUBLAS=1 \
-D WITH_V4L=ON \
-D WITH_QT=OFF \
-D WITH_OPENGL=ON \
-D WITH_GSTREAMER=ON \
-D OPENCV_GENERATE_PKGCONFIG=ON \
-D OPENCV_PC_FILE_NAME=opencv.pc \
-D OPENCV_ENABLE_NONFREE=ON \
-D OPENCV_PYTHON3_INSTALL_PATH=~/venv/lib/python3.5/site-packages \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv/opencv_contrib/modules \
-D PYTHON_EXECUTABLE=~/venv/bin/python \
-D PYTHON_DEFAULT_EXECUTABLE=~/venv/bin/python3.5 \
-D BUILD_EXAMPLES=ON ..

Configuring and generating are successful. However, when I tried to compile it. This error appears:

What is happening here?
