For comparison, here is how we test for fuse in libguestfs: dnl FUSE is optional to build the FUSE module. AC_ARG_ENABLE([fuse], AS_HELP_STRING([--disable-fuse], [disable FUSE (guestmount) support]), [], [enable_fuse=yes]) AS_IF([test "x$enable_fuse" != "xno"], [PKG_CHECK_MODULES([FUSE],[fuse], [AC_SUBST([FUSE_CFLAGS]) AC_SUBST([FUSE_LIBS]) AC_DEFINE([HAVE_FUSE],[1],[Define to 1 if you have FUSE.]) old_LIBS="$LIBS" LIBS="$FUSE_LIBS $LIBS" AC_CHECK_FUNCS([fuse_opt_add_opt_escaped]) LIBS="$old_LIBS" ], [enable_fuse=no AC_MSG_WARN([FUSE library and headers are missing, so optional FUSE module won't be built]) ]) ]) AM_CONDITIONAL([HAVE_FUSE],[test "x$enable_fuse" != "xno"]) [ https://github.com/libguestfs/libguestfs/blob/master/configure.ac#L744 ] Is there any reason not to use PKG_CHECK_MODULES?
