Hi,
I'm curious to know how do you install tesseract and leptonica for opencv on windows.
Do you use cppan ?
Can you build leptonica with cmake and use it after in tesseract and opencv ? --> If yes without changed the cmakelists I'm very interested
Install vcpkg (MS packager to install windows based open source projects) and use powershell command like so.vcpkg install tesseract:x64-windows-static. Dependency libraries like Leptonicawill be auto installed for you. The tesseract can be auto integrated to your VS project using.vcpkg integrate install.

if you want to build leptonica using opencv source you have to modify cmakelists.txt and then use this
