Problems finding the Leptonica and Tesseract libraries on Windows

[DarlyMR]

I don't know if I'm avoiding any steps in the implementation of this library, but from what I see it is impossible to find the external libraries with these paths in Windows, although I understand a little about why it has not been specified since these do not have an installation address per Defect and their official guides do not do so either.

After having manually specified where the libraries are, I receive several errors that are slightly different from each other but match the same error number "MSB8066":

I haven't built and tested the plugin and example app in Windows and Linux. This work is planned for the next couple of weeks. I will leave an update when a new plugin that has been built and tested on Windows and Linux has been published.

Hello, enjoying the plugin so far :) I've managed to integrate the dynamic lib into android app, but the similar issue happens like for the gentleman that authored the issue. ` user@192 example % flutter build ios Building com.company.aiflusseract for device (ios-release)... Automatically signing iOS for device deployment using specified development team in Xcode project: X76XXTPX5X Running pod install... 3.1s Running Xcode build...

To put it in short terms: Tried running the example app(changed only the apple dev account team reference) and this error occurs. Tried cleaning the .lock file and Pods directory, no luck there... Flutter doctor is all green-marked. Running flutter 3.19.6 and dart 3.3.4. Noticed in changelog that you tested on iOS simulator, but not on the real device?
