---------------------------------------------------------------------
This error normally occurs when ocrmypdf can't find the Leptonica
library, which is usually installed with Tesseract OCR. It could be that
Tesseract is not installed properly, we can't find the installation
on your system PATH environment variable.
The library we are looking for is usually called:
liblept-5.dll (Windows)
liblept*.dylib (macOS)
liblept*.so (Linux/BSD)
