Sure, that's something that can help avoiding unnecessary rebuilds.
However, elsewhere in this thread, Sergio has mentioned that cfitsio
contains a run-time check to enforce that an application was built with
exactly the same headers as the library itself. Indeed it does that when
opening files.
$ grep CFITSIO_VERSION * -R
cfileio.c: if (version != CFITSIO_VERSION)
cfileio.c: printf(" Version used to build the CFITSIO library = %f\n",CFITSIO_VERSION);
fitsio.h:#define CFITSIO_VERSION 3.33
longnam.h:#define fits_open_file(A, B, C, D)
ffopentest( CFITSIO_VERSION, A, B, C, D)
