Could you clarify your goal here?
Hopefully ;-)
Are you trying to link a static library build by CMake with a shared
library
built by CMake? I haven't tried that, but I assume it would work just as
well as the link of static library built by CMake to an external library.
I think this is closest to what I am trying to do.
In sum, I don't think there is any case where you have to explicitly
specify
-fPIC. CMake takes care of that for you.
I understand that in general static libs don't need to be compiled with
-fPIC since they're supposed to be linked with executables. In my case
they will eventually linked when I build a certain shared library. It
might make better sense to just package this code as a shared library,
but for the moment if I could figure out how SET_TARGET_PROPERTIES I
think I'd be in good shape.
ADD_LIBRARY(MyStatic STATIC ... )
SET_TARGET_PROPERTIES( MyStatic PROPERTIES COMPILE_FLAGS -fPIC)
Thanks--
