FindTBB is aCMake find package module forIntel® Thread Building Blocks (TBB).

To use FindTBB in your CMake project, the first step is to setup your CMake project script.

1. Put a copy of theFindTBB.cmake file to your project. The typically location iscmake/modules/FindTBB.cmake.

2. Add the module directory to the CMake modules path to yourCMakeLists.txt file.

   list(APPENDCMAKE_MODULE_PATH${PROJECT_SOURCE_DIR}/cmake/modules/)

3. Callfind_package in yourCMakeLists.txt file to find TBB header files and libraries. For example, a simple code might be,

   find_package(TBB)

4. Build your executable or library with TBB, again in your ```CMakeLists.txt file,

   # Add include dirctory and compile definitions for all targetsinclude_directories(${TBB_INCLUDE_DIRS})add_definitions(${TBB_DEFINITIONS})# Create your executable targetadd_executable(my_exec my_exec.cc)# Link your target with TBB librariestarget_link_libraries(my_exec${TBB_LIBRARIES})

The complete, exampleCMakeLists.txt file is,

cmake_minimum_required (VERSION 2.8.8)project (MyProject)# Add the project modules directory to the CMake modules search path.list(APPENDCMAKE_MODULE_PATH${PROJECT_SOURCE_DIR}/cmake/modules/)# Find TBB libraries and header filesfind_package(TBB)# Add include dirctory and compile definitions for all targetsinclude_directories(${TBB_INCLUDE_DIRS})add_definitions(${TBB_DEFINITIONS})# Create your executable targetadd_executable(my_exec my_exec.cc)# Link your target with TBB librariestarget_link_libraries(my_exec${TBB_LIBRARIES})

When runningcmake for your project you may need to specify the location of the TBB install directory, include directory, and/or library direcory. For example, if you have installed TBB in the/path/to/tbb directory,

$ cmake -DTBB_ROOT_DIR=/path/to/tbb .

FindTBB can also use theTBB_INSTALL_DIR orTBBROOT environment variables to specify the install directory of TBB.

$ export TBBROOT=/path/to/tbb$ cmake .

If TBB does not use standard install paths (e.g. the open source version of TBB), you will need to specify the include and library directory.

$ cmake -DTBB_INCLUDE_DIR=/path/to/tbb/include -DTBB_LIBRARY=/path/to/tbb/lib .
