dnl @synopsis ACX_CFITSIO([CFITSIO_DIR, CFITSIO_INCDIR,
dnl [ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]])
dnl This macro figures out if the CFITSIO libraries and header
dnl files are installed.
dnl You may wish to use these variables in your default LIBS and CFLAGS:
dnl
dnl LIBS="$CFITSIO_LIBS $LIBS"
dnl
dnl You may wish to use these variables in your default CFLAGS:
dnl
dnl CFLAGS="$CFLAGS $CFITSIO_CFLAGS"
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if CFITSIO
dnl is found (HAVE_CFITSIO are defined first), and ACTION-IF-NOT-FOUND
dnl is a list of commands to run it if it is not found.
