Try ...

./configure --with-nvsdk-prefix=$HOME/exrstuff/NVsdk/LIBS/libs/

although unless I miss my guess, the NVidia SDK is both libraries and
includes, and if you have both in $HOME/exrstuff/NVsdk (i.e.
$HOME/exrstuff/NVsdk/include and $HOME/exrstuff/NVsdk/lib) it should find
it. configure scripts look in '$prefix/include' and '$prefix/lib'
conventionally for header files and libraries.

If you've build the NVsdk - have you installed it, too? The EXR config may
be looking for files that are only created by the install step of the
NVsdk.

hope this helps,
