Can anyone offer some advice for getting a 3rd party tool to find
openexr/ilmbase via autoconf?
I've tried using AC_CHECK_LIB() on libIlmImf, which returns the
right link flags when the libs are installed to the default location,
but I'm wondering if there is a neater way of doing it that might find
the headers/libs in other locations.
I've seen the openexr.m4 file within the openexr distribution, which
seems to provide AM_PATH_OPENEXR(), but I'm not too sure about
the process of using it from a 3rd party app. I can only call that if I
copy the openexr.m4 file into my app directory, but I'm assuming
there's a way of using it from where the openexr installation has put
it on the system.
So anyway, I'm new to this autoconf business, so any tips on reliably
finding openexr or ilmbase would be much appreciated.
