Correct way to use TBB's CMake link target ?

[nyue]

Hi,

  I am using the TBB CMake config as per those in the archive of 2021.7.0

find_package(TBB 2020 REQUIRED)

add_executable(tbbi
  main.cpp)

target_link_libraries(tbbi
  TBB::tbb)

However, when I compile it, it errors out and appears to be using the systems header instead of the one I provided via the TBB_DIR directive

I am building my application on Ubuntu 18.04

[ 50%] Building CXX object CMakeFiles/tbbi.dir/main.cpp.o

Are there other targets I should use or do I need to augment the target provided by TBB config with specific <>_INCLUDE_DIRS ?

Kind regards

I figured out my own error. I was looking at some old TBB example that still include the now deprecated and removed header "task_scheduler_init.h" and hence it is pick up the that file.

I should not include that file in the first place.

I have studied new TBB example and the issue is resolved.
