Avi Halachmi (:avih)	cc17f852d5	[cmake] Don't fail if brotli is missing (#56894 ). The libs which cmake controls are commented out at include/freetype/config/ftoption.h and cmake un-comment each enabled library, but the brotli option was not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained defined even if brotli was missing/disabled/etc. Comment it such that cmake can control it, which means leaving it undefined if brotli is missing. * include/freetype/config/ftoption.h: Fix typo.	5 years ago
Werner Lemberg	3de1b8d0b0	[cmake] Add brotli support. * CMakeLists.txt (FT_WITH_BROTLI): New option. * builds/cmake/FindBrotliDec.cmake: New file.	5 years ago

Werner Lemberg	12351eeefa	CMakeLists.txt: Fix generation of DLL related stuff (#56852 ). Extract `version_info' variable from `builds/unix/configure.raw' and use the data to correctly set `LIBRARY_VERSION' and `LIBRARY_SOVERSION'. Also use the data to set `ft_version' field in `freetype2.pc'. Also fix the needed minimum version of HarfBuzz in `freetype2.pc'.	5 years ago
Werner Lemberg	3fa35aa420	* src/sfnt/sfwoff2.c (compute_ULong_sum): Fix undefined shift. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=16933	5 years ago
