Adds IMPORTED for the TBB::tbb alias target as otherwise cmake produces
the following error:
CMake Error: install(EXPORT "OpenCVModules" ...) includes target "opencv_core" which requires target "tbb" that is not in the export set.
This problem occurs with the defaults used by homebrew on macOS, which
compiles both static and shared versions of TBB and OpenCV.
- Recommended compiler checks:
- GCC: CV_GCC
- Clang: CV_CLANG
- fixed problem with CMAKE_CXX_COMPILER_ID=Clang/AppleClang mess on MacOSX
Details: cmake --help-policy CMP0025
- do not declare Clang as GCC compiler
OpenCV fails to detect tbb on a debug build if the platform has only installed
debug libraries. This PR adds an additional check to the tbb detect logic for
systems that only install tbb debug and not both tbb debug and release.
[~] Automatically tracked dependencies between modules
[+] Support for optional module dependencies
[+] Options to choose modules to build
[~] Removed hardcoded modules lists from OpenCVConfig.cmake, opencv.pc and OpenCV.mk
[+] Added COMPONENTS support for FIND_PACKAGE(OpenCV)
[~] haartraining and traincascade are moved outside of modules folder since they aren't the modules
