| − | 5. Compiler setup
| |
| − |
| |
| − | Download and install CMake from cmake.org. During installation, select the option 'Add CMake to the PATH for all users'.
| |
| − |
| |
| − | Go to Control Panel - System, and then to 'Advanced System Setting'. Go to the 'Advanced' tab and click on 'Environment Variables'.
| |
| − | Add the MinGW path to the Path variable (in this case, it is C:\Qt\Tools\mingw730_64\bin).
| |
| − |
| |
| − | 6. Install OpenCV and compile its libraries
| |
| − |
| |
| − | Download OpenCV from Sourceforge, then install it (file opencv-4.1.1-vc14_vc15.exe) into the C:\OpenCV\ directory.
| |
| − |
| |
| − | Then, go to the CMake directory (C:\Program Files\CMake\bin) and execute cmake-gui.exe.
| |
| − |
| |
| − | * Where is the source code: C:/OpenCV/sources
| |
| − | * Where to build the binaries: C:/OpenCV/opencv-build
| |
| − |
| |
| − | Click next.
| |
| − |
| |
| − | * Specify the generator for this project: MinGW Makefiles
| |
| − | * Specify native compilers
| |
| − | * Compilers C: C:\Qt\Tools\mingw730_64\bin\gcc.exe
| |
| − | * Compilers C++: C:\Qt\Tools\mingw730_64\bin\g++.exe
| |
| − |
| |
| − | Click configure for the first time.
| |
| − |
| |
| − | Then, a variable list should appear.
| |
| − |
| |
| − | * Check the box [X]WITH_QT
| |
| − | * Check the box [X]WITH_OPENGL
| |
| − |
| |
| − | Click configure for the second time. If the compiler complains about not finding the Qt5Config.cmake file, add the following variable:
| |
| − |
| |
| − | * Qt5_DIR = C:/Qt/5.13.0/mingw73_64/lib/cmake/Qt5
| |
| − |
| |
| − | and click configure for the third time.
| |
| − |
| |
| − | Some other variables should appear:
| |
| − |
| |
| − | * Qt5Concurrent_DIR = C:\Qt\5.13.0\mingw73_64\lib\cmake\Qt5Concurrent
| |
| − | * Qt5Core_DIR = C:\Qt\5.13.0\mingw73_64\lib\cmake\Qt5Core
| |
| − | * Qt5Gui_DIR = C:\Qt\5.13.0\mingw73_64\lib\cmake\Qt5Gui
| |
| − | * Qt5Test_DIR = C:\Qt\5.13.0\mingw73_64\lib\cmake\Qt5Test
| |
| − | * Qt5Widgets_DIR = C:\Qt\5.13.0\mingw73_64\lib\cmake\Qt5Widgets
| |
| − | * Qt5OpenGL_DIR = C:\Qt\5.13.0\mingw73_64\lib\cmake\Qt5OpenGL
| |
| − |
| |
| − | and others should be added:
| |
| − |
| |
| − | * CMAKE_BUILD_TYPE = Release
| |
| − | * QT_MAKE_EXECUTABLE = C:\Qt\5.13.0\mingw73_64\bin\qmake.exe
| |
| − | * Unckeck the box [ ]ENABLE_PRECOMPILED_HEADERS
| |
| − |
| |
| − | then click configure for the fourth time. When finished, click generate.
| |
| − |
| |
| − | Then, open a command prompt and, from the C:\OpenCV\opencv-build directory, execute
| |
| − |
| |
| − | mingw32-make -j 4
| |
| − | mingw32-make install
| |
| − |
| |
| − | Then, copy all the *.dll from C:\OpenCV\opencv-build\bin\ to C:\Qt\5.13.0\mingw73_64\bin\
