Originally created by @Izaron on GitHub (Feb 18, 2017).

CLion uses CMake, and I can't build it, for example, with OCR
I have installed tesseract and leptonica developer libraries

option (WITH_OCR "Build with OCR (Optical Character Recognition) feature" OFF)

When I trying to change "OFF" to "ON" and clean cmake and cmake folder, I get an errors

<...>
compilation terminated.
/bin/sh: -I/usr/include/leptonica: No such file or directory
lib_ccx/CMakeFiles/ccx.dir/build.make:62: recipe for target 'lib_ccx/CMakeFiles/ccx.dir/__/zvbi/decoder.c.o' failed
gmake[3]: *** [lib_ccx/CMakeFiles/ccx.dir/__/zvbi/decoder.c.o] Error 127
/bin/sh: -I/usr/include/leptonica: No such file or directory
gmake[3]: *** Waiting for unfinished jobs....
<...>

I tried change code in this part:

#if (WITH_OCR)
  find_package(PkgConfig)

  pkg_check_modules (TESSERACT REQUIRED tesseract)
  pkg_check_modules (LEPTONICA REQUIRED lept)

  set (EXTRA_LIBS ${EXTRA_LIBS} ${TESSERACT_LIBRARIES})
  set (EXTRA_LIBS ${EXTRA_LIBS} ${LEPTONICA_LIBRARIES})
  include_directories (${TESSERACT_INCLUDE_DIRS} ${LEPTONICA_INCLUDE_DIRS})
  set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -DENABLE_OCR")
#endif (WITH_OCR)

But got very strange behavior - this includies and define ENABLE_OCR is available only in ccextractor.c file.
Can anyone fix it? I would be very glad.

linux/build and linux/builddebug works very well with all additional libraries.

@cfsmp3 and others who have any serious experience in CMake
Can you see this diff and check commit by commit? https://github.com/CCExtractor/ccextractor/compare/master...Izaron:cmake-ocr?expand=1 (have not requested pull yet)
There was one missed library, using of static libraries and more small bugs as seems to me

https://github.com/CCExtractor/ccextractor/blob/master/docs/using_cmake_build.txt - see screenshot of current master CMake
screenshot from 2017-02-22 16-25-38

With my changes it builds OK...

Also, still can't get out what "STATIC" in linker mean.
As I understand, with static libs we should get working binary without any dependencies? But with both STATIC and non-static I get in virtual machine:

./ccextractor: error while loading shared libraries: libpng16.so.16: cannot open shared object file: No such file or directory
./ccextractor: error while loading shared libraries: libtesseract.so.3: cannot open shared object file: No such file or directory

Can anyone help me please?
CMakeLists.txt have to be updated - we should change minor version from 77 to 85, add SWSCALE from FFMPEG, and get it working.

I've never used CMake, this was Anshul's work I think.
