Some influential environment variables:

 CC          C compiler command
 CFLAGS      C compiler flags
 LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
             nonstandard directory <lib dir>
 CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
             headers in a nonstandard directory <include dir>
 CPP         C preprocessor

Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.
