hi, I want to build opencv-4.5.4 + Tesseract-5 with cmake

**(1)** i downloaded this file (64 bit) :  
[Binaries](https://tesseract-ocr.github.io/tessdoc/Home.html#binaries) \> [Tesseract installer for Windows](https://github.com/UB-Mannheim/tesseract/wiki#tesseract-installer-for-windows) \> [tesseract-ocr-w64-setup-v5.0.0-rc1.20211030.exe](https://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-w32-setup-v5.0.0-rc1.20211030.exe)  
but i don’t know how set these 3 inputs [see img1] :

1. Tesseract\_DIR
2. Tesseract\_INCLUDE\_DIR
3. Tesseract\_LIBRARY

**(2)** i went to this link [[Compilation guide for various platforms](https://tesseract-ocr.github.io/tessdoc/Compiling.html#windows) ] and build tesseract from this method [[For visual studio project using tesseract](https://tesseract-ocr.github.io/tessdoc/Compiling.html#for-visual-studio-project-using-tesseract) ] —\> after build end —\> this is result :

i set these 3 inputs [see img1] like this :

1. Tesseract\_DIR :  
empty!
2. Tesseract\_INCLUDE\_DIR :  
C:\Users\mahdi\vcpkg\installed\Tesseract-x64-windows\include
3. Tesseract\_LIBRARY :  
C:\Users\mahdi\vcpkg\installed\Tesseract-x64-windows\lib

after press configure button [in cmake] → i saw Tesseract not installed! :

How can I solve this problem? I want to build opencv with Tesseract but I can’t ☹

k i found answer 😑  
i added tesseract paths to Environment Variables :

Then I restarted cmake, Then I deleted [cleaned] these 3 inputs [see img1]  
then press Configure button in cmake, Tesseract found! 😑
