[Fontconfig] distribute font with application

[Peter Shinners]

How can an application add extra "font" directories at startup? Is there 
an environment variable that allows adding directories to the fontconfig 
search path?

We have a few .ttf files we would like to distribute internally with an 
application. This is using Qt4 built with fontconfig support. Adding the 
fonts to all user's or all system's font directories is not a good option.

These are systems running CentOS4, fontconfig version 2.2.3.
