CCExtractor version: v94

Necessary information

I'm trying to compile ccextractror with hardsubx support on macOS 12.6 (Intel), I'm following instructions at https://github.com/CCExtractor/ccextractor/blob/master/docs/COMPILATION.MD#using-cmake and no matter what I do I approach the fail:

In file included from /Users/medikoo/Projects/ccextractor/src/lib_ccx/ccx_encoders_common.c:10:
/Users/medikoo/Projects/ccextractor/src/ccextractor.h:10:10: fatal error: 'leptonica/allheaders.h' file not found
#include <leptonica/allheaders.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
make[2]: *** [lib_ccx/CMakeFiles/ccx.dir/ccx_encoders_common.c.o] Error 1
make[1]: *** [lib_ccx/CMakeFiles/ccx.dir/all] Error 2
make: *** [all] Error 2

I definitely have leptonica installed (via brew), and see the mentioned headers file at /usr/local/Cellar/leptonica/1.82.0_1/include/leptonica/allheaders.h. I've attempted to run compilation with PATH="/usr/local/Cellar/leptonica/1.82.0_1/include:$PATH" but it didn't change anything.

Why exactly make command doesn't see this headers file, and what can I do to fix it?

Can you try setting CPATH to $CPATH:/usr/local/Cellar/leptonica/1.82.0_1/include/ and rerunning make:

$ CPATH="$CPATH:/usr/local/Cellar/leptonica/1.82.0_1/include/" make

Is this still an issue on the latest master?

I'm closing this because

Lack of activity from OP
Can't reproduce (I do get an error on Mac, but it's past the header stage - it's linking).
I don't think we are actively maintaining Mac to be honest.
