What is the "right way" to express the use of OpenCL with CMake >= 3.14?

Question

Years ago, before CMake 3, we would write:

find_package(OpenCL REQUIRED)
include_directories(${OPENCL_INCLUDE_DIR})
target_link_libraries(my_app ${OPENCL_LIBRARY})

... but that's not idiomatic today. We use targets and target dependencies. But - what are these targets for OpenCL? What OpenCL target should my_app depend on?

I'm specifically interested in how thing stand with CMake 3.14 and earlier (in case things changed with CMake 3.8 or some other version.) if not - any range of version would do.

Answer 1

This is how it should work today:

find_package(OpenCL REQUIRED)
target_link_libraries(my_app OpenCL::OpenCL)

and that should take care of includes and link libraries.
