CLA signed - thank you for your contribution !
Adding release notes for 2.0.1
cmake: use ${CMAKE_INCDIR_BASE} instead of hard-coding "include"
cmake: move all headers to include/opensubdiv/

The base include/ directory is too general for general
installation.  Specifically, "include/version.h" will likely
clash with many other projects.

Move headers to include/opensubdiv/ to prevent filesystem
namespace clashes.
