that's a bit more complicated... You need to write a macro that checks for 
Coin and for OpenInventor and set a variable if one of them was found.

You can find examples for macros in kdevelop HEAD CVS, check the 
kdevelop.m4.in file. The last check there checks for Qt >= 3.0.5 and sets the 
QEDITOR_SUBDIR accordingly. Then you add that macro to configure.in.in so 
that it will be executed in the configure script. After that you can use the 
variable defined in AC_SUBST (in this case, QEDITOR_SUBDIR) in Makefile.am, 
check parts/Makefile.am for an example.

I know that it is tricky, you can find more background information on the 
auto* tools on www.andamooka.org.

Good luck,
Harry
