Probably it fixed in: https://savannah.nongnu.org/bugs/index.php?55235 Can you try it?

I dont't quite understand why both cmake and autoconf scripts edit ftoption.h. Isn't it enough to add a compile option -DFT_CONFIG_OPTION_USE_HARFBUZZ?

The same question applies to ZLIB, BZIP2, and PNG as well.

If CMakeList.txt is happy to remove comment around FT_CONFIG_OPTION_USE_HARFBUZZ, it should not be shy to put it back.

Compiling freetype with harfbuzz requires in src/autofit/afscript.h:35:          HB_SCRIPT_ADLAM.

HB_SCRIPT_ADLAM was introduced in harfbuzz 1.3.0, so the build system (cmake) is supposed to check, whether harfbuzz >= 1.3.0 is installed, in order to enable FT_WITH_HARFBUZZ.

If I switch FT_WITH_HARFBUZZ off, and move include/harfbuzz to include/harfbuzz.bak, make fails with

In file included from /src/freetype-2.10.0/src/autofit/afglobal.h:26,
                 from /src/freetype-2.10.0/src/autofit/afcjk.c:29,
                 from /src/freetype-2.10.0/src/autofit/autofit.c:24:
/src/freetype-2.10.0/src/autofit/afshaper.h:29:10: fatal error: hb.h: No such file or directory
 #include <hb.h>

So it seems HARFBUZZ is not optional, but required and in this case there is no need for the option FT_WITH_HARFBUZZ.

In turn the chicken-and-egg interdependency mentioned in INSTALL.UNIX is not solvable anymore.
