 1337 Installation directories:
 1338   --prefix=PREFIX         install architecture-independent files in PREFIX
 1339                           [$ac_default_prefix]
 1340   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1341                           [PREFIX]
 1342 
 1343 By default, \`make install' will install all the files in
 1344 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1345 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1346 for instance \`--prefix=\$HOME'.

 1403   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1404               nonstandard directory <lib dir>
 1405   LIBS        libraries to pass to the linker, e.g. -l<library>
 1406   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1407               you have headers in a nonstandard directory <include dir>
 1408   PKG_CONFIG  path to pkg-config utility
 1409   PKG_CONFIG_PATH
 1410               directories to add to pkg-config's search path
 1411   PKG_CONFIG_LIBDIR
 1412               path overriding pkg-config's built-in search path
 1413   LIBUSB_CFLAGS
 1414               C compiler flags for LIBUSB, overriding pkg-config
 1415   LIBUSB_LIBS linker flags for LIBUSB, overriding pkg-config
 1416   UDEV_CFLAGS C compiler flags for UDEV, overriding pkg-config
 1417   UDEV_LIBS   linker flags for UDEV, overriding pkg-config
 1418 
 1419 Use these variables to override the choices made by `configure' or to help
 1420 it to find libraries and programs with nonstandard names/locations.

 3036 on the command line, even when the '-f' option is present.  This is contrary
