# Specifying Custom Paths

By default, none of these options should be required unless you want &app; to use a specific version of a development package, or if the configure test fails to find a component. Please report the problem if a configure test fails.

The following custom path options are available:

`--with-plugins-install=user|system|prefix` | This option sets the install policy for NPAPI (mozilla) and KPARTS (kde) plugins. Policy 'user' means plugin will be installed only for the configuring user. Policy 'system' will try to find a systemwide place for plugins (to enable for all). Policy 'prefix' will install under ${prefix} (npapi/kparts subdirs); WARNING: if 'prefix' policy is given, plugins won't be found w/out further enabling procudures. The default policy is 'user', can be overridden for specific plugins.
`--with-npapi-install=user|system|prefix` | This option sets the install policy for NPAPI plugin. Policy 'user' means plugin will be installed in ~/.mozilla/plugins; 'system' will try to find an existing system-wide mozilla plugin dir (or bail out if not found); 'prefix' will install under ${prefix}/npapi.
`--with-npapi-plugindir` | This is the directory to install the NPAPI (Mozilla) plugin in. By default it goes to ~/.mozilla/plugins.
`--with-kparts-install=user|system|prefix` | This option sets the install policy for all KPARTS (kde) files. Policy 'user' means plugin will be installed in ~/.kde; 'system' will find out using kde-config (or bail out if not found); 'prefix' will install under ${prefix}/kparts. The actual prefix can be overridden using `--with-kde-pluginprefix` or the fine-tuned options. The default at time of writing (2008-05-18) is 'user'.
`--with-kde-pluginprefix` | This option sets the default install dir for all KPARTS (kde) files. The plugin will be installed in PREFIX/lib/kde3, use `-with-kde-plugindir` to override. The service file in PREFIX/share/services, use `--with-kde-servicesdir` to override. The config file in PREFIX/share/config, use `--with-kde-configdir` to override. The appdata file in PREFIX/share/apps/klash, use `--with-kde-appsdatadir` to override.
`--with-kde-plugindir` | This is the directory to install the KPARTS (kde) plugin in. By default it is what's set by --with-kde-pluginprefix or what's returned by kde-config --install module --expandvars, or $(prefix)/share/services if kde-config is not found.
`--with-kde-servicesdir` | This is the directory to install the KPARTS (kde) service in. By default it is what's set by --with-kde-pluginprefix or what's returned by kde-config --install services --expandvars, or $(libdir)/kde3 if kde-config is not found.
`--with-kde-configdir` | This is the directory to install the KPARTS (kde) config files in. By default it is what's set by --with-kde-pluginprefix or what's returned by kde-config --install config --expandvars, or $(prefix)/share/config if kde-config is not found.
