Hi everyone,
I’m reposting here the same question I’ve already posted on Stackoverflow [1],
in the hopes of reaching a more appropriate audience.
I have an imported target (an external library) that required -ldl, so I'm
adding ${CMAKE_DL_LIBS} to the INTERFACE_LINK_LIBRARIES property like this:
set_property(TARGET some_lib PROPERTY
INTERFACE_LINK_LIBRARIES Threads::Threads ${CMAKE_DL_LIBS})
Now, when I use that target elsewhere, like this:
target_link_libraries(my_target some_lib)
I get a linker error that `dladdr` is undefined. However, when I explicitly add
CMAKE_DL_LIBS to that target, it works:
target_link_libraries(my_target some_lib ${CMAKE_DL_LIBS})
So it seems that this is not propagate correctly. Is there a way to make this
work without explicitly specifying CMAKE_DL_LIBS in the using target?
Kind regards,
Björn Pollex
