# Search TBB library (4.1 - 4.4, 2017) |

|
# Own TBB (3rdparty/tbb): |
|
# - set cmake option BUILD_TBB to ON |
|
# |
|
# External TBB (from system): |
|
# - Fedora: install 'tbb-devel' package |
|
# - Ubuntu: install 'libtbb-dev' package |
|
# |
|
# External TBB (from official site): |
|
# - Linux/OSX: |
|
# - in tbbvars.sh replace 'SUBSTITUTE_INSTALL_DIR_HERE' with absolute path to TBB dir |
|
# - in terminal run 'source tbbvars.sh intel64 linux' ('source tbbvars.sh' in OSX) |
|
# - Windows: |
|
# - in terminal run 'tbbvars.bat intel64 vs2015' |
|
# |
|
# Return: |
|
# - HAVE_TBB set to TRUE |
|
# - "tbb" target exists and added to OPENCV_LINKER_LIBS |
