I experiment with the TBB composite node and the TBB CMake scripts.
My test repository https://github.com/thedarksideofthemoon/tbb-test works fine when I compile it using GCC 5.4 at Ubuntu 16.04. However, I cannot get my test program to compile with Clang 6.0. Instead, I get the compiler error error: unknown template name 'composite_node'.
Do I need any additional flags to find the composite_node?
I have checked your tbb-test example on Ubuntu 16.04 with clang 6.0 and everything is ok. Could you please compile test_composite_node with stdver=c++11 enabled?
