On distributions like NixOS, which build packages in a sandbox,
fontconfig configuration files may not be available at build time,
which leads to the following cmake warnings even if the font itself is
available:
Fontconfig error: Cannot load default config file
CMake Warning at CMakeLists.txt:62 (message):
Could not find font FreeSans!
This commit allows to specify exact font location on cmake commandline
via -DTT_FONT_FILE=... When specified, automatic font look up via
fc-list is skipped.
