- Protect against the case when the user has multiple installs of TBB in their search paths and the first install does not contain debug libraries. In this case it is possible to get mismatched versions of TBB inserted into TBB_LIBRARIES. - Also suppresses warning about use of TBB_ROOT on modern versions of CMake due to CMP0074.

# TBB_COMPATIBLE_INTERFACE_VERSION - The oldest major interface version

# ENV TBB_ROOT or just TBB_ROOT - root directory of tbb installation
|
|
# ENV TBB_BUILD_PREFIX - specifies the build prefix for user built tbb
|
|
# libraries. Should be specified with ENV TBB_ROOT
|
|
# and optionally...
|
|
# ENV TBB_BUILD_DIR - if build directory is different than ${TBB_ROOT}/build
