FreeType compilation

Required for macOS only.

This page explains how to recompile the FreeType dependency on every platforms.

Note: Unfortunately, HomeBrew's precompiled FreeType cannot be used, because of the macOS deployment target.

Create the precompiled freetype package:

cd ~/software
wget http://download.savannah.gnu.org/releases/freetype/freetype-2.9.tar.bz2
tar jxf freetype-2.9.tar.bz2
cd freetype-2.9
export MACOSX_DEPLOYMENT_TARGET=10.9
./configure --without-zlib --without-bzip2 --without-png
make -jX
cd ..
tar -cvjSf macos-precompiled-freetype-2.9.tar.bz2 freetype-2.9
