How can I get the list of dependencies of cmake ta

问题:

For instance, how can I know if my executable target E depends on my library target L?

Let's image E depends on L1 and L2, but I don't know if they depend on L.

target_link_libraries(E L1 L2)

I'd like to get the list from cmake itself before calling target_link_libraries, so that I can do some tricks if I detect that E depends on two libraries which are incompatible. I played a bit with GetPrerequisites, but this finds out dependencies on existing libraries which are on disk, not on target which are being built.

thanks

You can use CMake's "dependency graphs generator". Please read this link for details

cmake --graphviz=test.dot . ...
