Sourcing the file installed on dragnipur is causing a CMake error. I
don't know if it is an install error or a problem with FindTBB.cmake,
but this should get around the problem by just using the "old" method
for finding TBB.
The latest version of TBB changes the include directory where the
version is stored, so the old version of FindTBB.cmake would fail
because it could not open this file. This issue has already been fixed
by the FindTBB.cmake in VTK, so pull the latest version of that.
The FindTBB.cmake module gets the TBB version by reading and grepping
one of the header files. Before doing so, it checks to see if the
version variable already exists. The problem was it was checking
TBB_VERSION, which was never created. Worse, other build systems might
set this for us (for example, the ParaView superbuild). Correct this by
making sure both TBB_VERSION_MAJOR and TBB_VERSION_MINOR are set.
In the FindTBB module, add the directory of the TBB includes and the
directory of the base tbb library to the list of paths to search for
TBB includes and libs, respectively. The reason is that TBB has its
initial includes and libraries and then has its support libraries.
Rather than enter entire paths 9 separate times, this allows you to
select the include directory once and one TBB library and the rest will
be automatically populated.
