  1247 By default, \`make install' will install all the files in
  1248 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
  1249 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
  1250 for instance \`--prefix=\$HOME'.
  1251 
  1252 For better control, use the options below.

  1308   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
  1309               nonstandard directory <lib dir>
  1310   LIBS        libraries to pass to the linker, e.g. -l<library>
  1311   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
  1312               you have headers in a nonstandard directory <include dir>
  1313   PKG_CONFIG  path to pkg-config utility
  1314   PKG_CONFIG_PATH
  1315               directories to add to pkg-config's search path
  1316   PKG_CONFIG_LIBDIR
  1317               path overriding pkg-config's built-in search path
  1318   SDL_CFLAGS  C compiler flags for SDL, overriding pkg-config
  1319   SDL_LIBS    linker flags for SDL, overriding pkg-config
  1320   XMKMF       Path to xmkmf, Makefile generator for X Window System
  1321   CPP         C preprocessor
  1322 
  1323 Use these variables to override the choices made by `configure' or to help
  1324 it to find libraries and programs with nonstandard names/locations.
