OpenSubdiv/CMakeLists.txt
David G Yu dbb75b650c Find TBB using TBB's CMake config 
Updated the CMake build to locate TBB using TBB's CMake config
and deleted the local cmake/FindTBB.cmake module.

While the source code remains compatible with earlier versions of
TBB, updated the minimum TBB version from 4.4 to 2018 since that
is the earliest TBB release to include a CMake config.  This is
the version of TBB specified for the CY2019 VFX Reference Platform.

Tested on Windows, Linux, and macOS using TBB 2018 Update 6,
TBB 2020 Update 3, and oneTBB 2021.10.0
