wrapper_capi.h:1:10: fatal error: 'tesseract/capi.h' file not found

I'm sure that I'm doing something stupid.

Windows 10. (I have tried linux and mac with 0 issues 👍🏽 , but alas, the deployment target for this binary is Windows... 👎🏽 )

Trouble being...

The header does seem to be there....

I ended up using std::process::Command and calling the compiled version of tesseract-ocr... it's dirty but working. Would love to know what was up with this though...

Hey, sorry you couldn't get it working :(

I've tried to replicate on my Windows install, but unfortunately I can't even get as far as you. I think something may be up with my install- I don't use Windows that often.

I am going to transfer this issue to the https://github.com/ccouzens/tesseract-sys because I think the issue is about that.

thanks anyway -- it works PERFECTLY on mac and linux (which is where I usually am). So, thank you for all the hard work on the crate, it's awesome :)
