CMake error with OpenCV 3.2/contrib on .dnn directory
I am using CMake 3.8.1 and downloaded OpenCV 3.2 and opencv_contrib_master at the same time from Github.
I specified the opencv_contrib_master directory in the OPENCV_EXTRA_MODULES_PATH line.
I also deselected at least protobuf and BUILD_opencv_dnn.
However, when I try and configure in CMake I get an error saying:
CMake Error at cmake/OpenCVModule.cmake:294 (add_subdirectory):
The binary directory
C:/OpenCV/build/modules/dnn/.dnn
is already used to build a source directory. It cannot be used to build
source directory
D:/opencv_contrib-master/modules/dnn
Specify a unique binary directory name.
Call Stack (most recent call first):
modules/CMakeLists.txt:7 (ocv_glob_modules)
What should I do to clear this error?I completely deleted the opencv and the contrib directories and downloaded the packages from GitHub within 2 minutes. I deselected aruco and bioinspired. I specified the proper contrib directory for the AXTRA_MODULES_PATH. Now I get:
CMake Error at D:/opencv/cmake/OpenCVUtils.cmake:850 (file):

Any help appreciated.
