  1248 By default, \`make install' will install all the files in
  1249 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
  1250 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
  1251 for instance \`--prefix=\$HOME'.
  1252 
  1253 For better control, use the options below.

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