I want to install openbr in windows. I use VS2015 and Qt5.8 and CMake3.7win64x64 and opencv3.2. (in http://openbiometrics.org/docs/install/index.html#windows has pointed use VS2013, OpenCV2.4.11, Qt5.4.1 but i don't know, the problem relate to versions or not?!) when i type: cmake -G "NMake Makefiles" -DBUILD_PERF_TESTS=OFF -DBUILD_TESTS=OFF -DWITH_FFMPEG=OFF -DCMAKE_BUILD_TYPE=Debug .. in VS2015x86x64 Cross Tools Command Prompt i get this error: 

cmake -G "NMake Makefiles" -DBUILD_PERF_TESTS=OFF -DBUILD_TESTS=OFF -DWITH_FFMPEG=OFF -DCMAKE_BUILD_TYPE=Debug ..

what's the problem?

I should send as comment but I cannot. I tried OpenBR yesterday and face some version problem,too. But In your question, It seems it is the problem of Building openCV.

I saw that your error message is the same as your command. Is there any copy-paste error?

Since this step seems nothing to do with QT, I used VS2015, openCV3.0 and cmake 3.5.1

what I did is:

  1. mkdir build-msvc2015
  2. cd build-msvc2015
  3. cmake -G "NMake Makefiles" -DBUILD_PERF_TESTS=OFF -DBUILD_TESTS=OFF -DWITH_FFMPEG=OFF -DCMAKE_BUILD_TYPE=Debug ..

and worked fine. It would face some problem if you don't cd to the folder or the folder have already something in that.So I think the later version of openCV and visual studio would be fine in this step.

  • thanks. I solved this problem. i hadn't downloaded opencv2.4.11 that offer http://openbiometrics.org and so CMakeLists.txt was not in this folder. after that i downloaded [OpenCV 2.4.11](https://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.11/opencv-2.4.11.zip/download) my problem is solved. –  Mar 07 '17 at 20:05
  • but i have other question. when i build OpenBR on windows and when i type following code on `VS2015 x86 x64 Cross Tools Command Prompt` : `cmake -G "CodeBlocks - NMake Makefiles" -DCMAKE_PREFIX_PATH="C:/opencv-2.4.11/build/install;C:/Qt/Qt5.4.1/5.4/msvc2013_64" -DCMAKE_INSTALL_PREFIX="./install" -DBR_INSTALL_DEPENDENCIES=ON -DCMAKE_BUILD_TYPE=Release ..` i get this error : `CMake Error at CMakeLists.txt:88 (find_package): Found package configuration file: C:/opncv2.4.11/../OpenCVConfig.cmake but it set OpenCV_FOUND to FALSE so package "OpenCV" is considered to be NOT FOUND.` –  Mar 07 '17 at 20:26
  • it seems that your cmake cannot find your opencv, two possible solutions: 1.the path of opencv is wrong. the path in the document was wrong, it build opencv in the C:/open-2.4.11/build-msvc2013/ , but it search the opencv in the C:/open-2.4.11/build, so it cannot find it. 2.add OpenCV_DIR to your environment variables, variable name: OpenCV_DIR variable value: the build folder of your opencv(ex:C:/open-2.4.11/build). I don't know why but it worked for me even if i give wrong opencv path to cmake – ggininder Mar 08 '17 at 02:07
