# GvdB: This module uses the environment variable TBB_ARCH_PLATFORM which defines architecture and compiler.
# e.g. "ia32/vc8" or "em64t/cc4.1.0_libc2.4_kernel2.6.16.21"
# TBB_ARCH_PLATFORM is set by the build script tbbvars[.bat|.sh|.csh], which can be found
# in the TBB installation directory (TBB_INSTALL_DIR).
#
# GvdB: Mac OS X distribution places libraries directly in lib directory.
#
# For backwards compatibility, you may explicitely set the CMake variables TBB_ARCHITECTURE and TBB_COMPILER.
