[CMake] linking question

[Petr Kmoch]

Hi Bill.

Probably the easiest way to set the interface properties to just what you
need is to use the PUBLIC (which is the default), PRIVATE and INTERFACE
keywords when specifying dependencies. In your case, you'd apply them like
this:

add_library(joe STATIC joe.c joe_a.c)
add_library(fred SHARED fred.c fred_a.c)
target_link_libraries(fred PRIVATE joe)  # PRIVATE means it will not form
part of the transitive linking interface

add_executable(mike mike.c)
# mike only contains calls to functions in fred
target_link_libraries(mike fred)

I hope this helps.

Petr
