    _______________________________________________________

Details:

when checking for SUNDIALS API compatibility
the configure scripts uses previously detected
values for SUNDIALS_IDA_LIBS, SUNDIALS_NVECSERIAL_LIBS, KLU_LIBS
but it doesn't use corresponding values for CPPFLAGS and LDFLAGS.

This causes the check for a compatible SUNDIALS API to fail
even if a working version of SUNDIALS is installed but is located
in a non standard path.

I have a patch that solves the issue for me, 
it is created against dev branch but I think it could 
go into stable as well.

I Will attach the patch later once I have a bug number.
