AC_CHECK_LIB cannot test for a function with C++ linkage.  A C++ function's
symbol name depends on the types of its parameters as well as its name; this
makes features like overloading possible.  AC_CHECK_LIB does not know about the
parameters, so it cannot craft a test.

If libIlmImf contains a function with C linkage, you could test for it.  If not,
you could test linking a trivial `int main() { return 0; }' with -lIlmImf.
