Your explanation is quite strange for me: you want to build application that use tesseract in environment where you can not build/install tesseract???
Anyway it your problem: installed header your can find here: https://github.com/tesseract-ocr/tesseract/blob/267b79982d64e48d11eaa99ee2618106662a9b10/CMakeLists.txt#L319 Minimum of the header will depend on maxim of tesseract usage ;-) e.g. capi.h header will be needed if you will use it C-API... ocrclass.h should be needed only in case you want to use progress/cancel function etc. Zdenko so 24. 11. 2018 o 15:57 'Yuliana Zigangirova' via tesseract-ocr < tesseract-ocr@googlegroups.com> napísal(a): > Thank you for your answer.
