NAME
FcConfigSetSysRoot - Set the system root directory
SYNOPSIS
#include <fontconfig/fontconfig.h>
void FcConfigSetSysRoot (FcConfig *config, const FcChar8 *sysroot);
DESCRIPTION
Set 'sysroot' as the system root directory. All file paths used or created with this 'config' (including
file properties in patterns) will be considered or made relative to this 'sysroot'. This allows a host to
generate caches for targets at build time. This also allows a cache to be re-targeted to a different base
directory if 'FcConfigGetSysRoot' is used to resolve file paths. When setting this on the current config
this causes changing current config (calls FcConfigSetCurrent()).
