Usage as git submodule with cmake

[maxbachmann]

Whats the correct way to use taskflow as git submodule. I tried to use it in the following way:

set(TF_BUILD_CUDA OFF CACHE BOOL "Enables build of CUDA code")
set(TF_BUILD_TESTS OFF CACHE BOOL "Enables build of tests")
set(TF_BUILD_EXAMPLES OFF CACHE BOOL "Enables build of examples")

add_subdirectory(extern/taskflow)
...
target_link_libraries(target tf::default_settings)

However this fails when compiling with the error:

fatal error: taskflow/taskflow.hpp: No such file or directory
      4 | #include <taskflow/taskflow.hpp>

I could not find any documentation on how to add taskflow as a submodule.

Since taskflow is header only I am currently working around this by using

set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)
...
target_include_directories(target PRIVATE extern/taskflow/)
target_link_libraries(target Threads::Threads)

You should be able to just link to the Taskflow CMake target after adding the subdirectory:

target_link_libraries(${PROJECT_NAME} PUBLIC Taskflow)

Thanks @burgholzer. This works as expected 👍
