where is the source code : C:/leptonica-1.77.0
where to build binaries : C:/leptonica-1.77.0/build
click Configure button select compiler
see "Configuring done" click Generate button and see "Generating done"
Open Visual Studio 2015 >> file >> open "C:\leptonica-1.77.0\build\build\INSTALL.vcxproj" select release, build INSTALL

Step 2.download https://codeload.github.com/tesseract...
extract it in a dir like "C:\tesseract-4.0.0"
run cmake
where is the source code : C:/tesseract-4.0.0
where to build binaries : C:/tesseract-4.0.0/build
click Configure button select compiler
see "Configuring done" click Generate button and see "Generating done"
Open Visual Studio 2015 >> file >> open "C:/tesseract-4.0.0\build\ALL_BUILD.vcxproj" build INSTALL
Step 3. in OpenCV cmake set Tesseract_INCLUDE_DIR : C:/Program Files/tesseract/include
set tesseract_LIBRARY C:/Program Files/tesseract/lib/tesseract40.lib
set Lept_LIBRARY C:/Program Files/leptonica/lib/leptonica-1.77.0.lib
