How to build Harfbuzz and freetype2

gistfile1.txt

I am very sorry that I can only help you incompletely.

(1) I believe this site is helpful to build harfbuzz and freetype libraries.

http://www.gregwessels.com/dev/2017/05/02/freetype-harfbuzz.html

 - c:/usr/local/lib/freetype.lib
 - c:/usr/local/lib/freetype.dll
 - c:/usr/local/include/ft2build.h
 - c:/usr/local/include/freetype/*.h
 - c:/usr/local/lib/harfbuzz.lib
 - c:/usr/local/lib/harfbuzz.dll
 - c:/usr/local/include/harfbuzz/*.h

(2) Currently freetype module requires PKG-CONFIG, so to change CMakeLists.txt in modules/freetype is needed.
And add Entry "FREETYPE_INCLUDE_DIRS" and "HARFBUZZ_INCLUDE_DIRS" with cmake configuration.

> FREETYPE_INCLUDE : c:/usr/local/include/

> HARFBUZZ_INCLUDE : c:/usr/local/include/harfbuzz

      if(PKG_CONFIG_FOUND)
        pkg_search_module(FREETYPE freetype2)
        pkg_search_module(HARFBUZZ harfbuzz)
      endif()
    
    if(NOT FREETYPE_FOUND)
      if( FREETYPE_INCLUDE_DIRS )
        set ( FREETYPE_FOUND YES)
      endif()
    endif()
    
    if(NOT HARFBUZZ)
      if( HARFBUZZ_INCLUDE_DIRS )
        set ( HARFBUZZ_FOUND YES)
      endif()
    endif()

(3) Build OpenCV with those dlls, but ...
Linking opencv with static libraries looks like good.
However to link with dll failed...
