+
+## Build
+

+# build ttf-parser C API first
+cargo build --release --manifest-path ../../c-api/Cargo.toml
+
+# build only with ttf-parser support
+qmake
+make
+
+# or build with freetype support
+qmake DEFINES+=WITH_FREETYPE
+make
+
+# or build with harfbuzz support
+# note that harfbuzz should be built from sources using meson,
+# because we're using an unstable API
+#
+# build harfbuzz first
+meson builddir -Dexperimental_api=true --buildtype release
+ninja -C builddir
