${prefix} expansion in configure.ac ?

[Philippe Trottier <tchiwam@xxxxxxxxxx>]

I have a little trouble here, I am trying to add the destination 
directory "--prefix" to the library and header directorys to look in... 
but since I am using ${libdir} and ${includedir} I get this

CPPFLAGS=-I${prefix}/include
LDFLAGS=-L${exec_prefix}/lib

and not /home/user/include and /home/user/home ...

I am trying to get the autoconf script to be easy to install in a home 
directory instead of needing the "su" power to install, and also prevent 
the need to change LD_LIBRARY_PATH etc... etc...

Is there better way to expand ${prefix} other than using sed ?

Yours,
Phil

AC_MSG_CHECKING([prefix for libraries and headers])
AC_ARG_ENABLE([search-prefix],
       AC_HELP_STRING([--enable-search-prefix],
              [search installation location for libraries and headers. 
[[Default=yes]]]),
       ,
       enableval="yes"
           )

if test "$enableval" = "yes" ; then
    AC_MSG_RESULT([yes])
    AC_MSG_CHECKING([Headers directory at])
    test -d $includedir && echo YES
    CPPFLAGS="-I$includedir $CPPFLAGS" &&
    AC_MSG_RESULT($includedir)
    AC_MSG_CHECKING([Library directory at])
    test -d $libdir && echo YES
    LDFLAGS="-L$libdir $LDFLAGS" &&
    AC_MSG_RESULT($libdir)
else
    AC_MSG_RESULT([no])
