let’s say we do want to mess with cmake. What is the typical way to add the shared rule?
   - patch Makefile.standalone in exodusii.py?
   - repackage exodus and serve it from the petsc servers?
Is there a BuildSystem way to know that the linker flag to build a shared library is -shared under linux and -dynamiclib under mac OS? If so, can we simply build the shared library in exodusii.py?
