Switch to using a C extension module to interface with fontconfig. This means that calibre now has a build time dependency on fontconfig as well. You can tell calibre where to find the font config headers and library via the environment variables: FC_INC_DIR and FC_LIB_DIR

It can be used to find all fonts available on the system as well as the closest
match to a given font specification. The main functions in this module are:
