[CMake] Problem with IMPORTED_LINK_INTERFACE_LIBRARIES_<config>

[Michele Santullo]

Hello, I need to add some linker dependencies to a static lib I'm 
importing into our project. I need to do that on a per-target basis, but 
the following is not working:

add_library(GameNet STATIC IMPORTED) # our code built in another project 
and imported by the current one
add_library(Library STATIC IMPORTED) # 3rd party library, source code 
unavailable
add_library(LibraryD STATIC IMPORTED) # Debug version of the same 
library as above

set (ALL_LIBS
     optimized Library
     debug LibraryD
)

set_target_properties(GameNet PROPERTIES 
IMPORTED_LINK_INTERFACE_LIBRARIES "${ALL_LIBS}")

Running cmake gives a message about optimized/debug keyword being 
forbidden in this case. The same message suggests you use 
IMPORTED_LINK_INTERFACE_LIBRARIES_<config> in this case. However, I 
tried the following:

set_target_properties(GameNet PROPERTIES 
IMPORTED_LINK_INTERFACE_LIBRARIES_DEBUG LibraryD)
set_target_properties(GameNet PROPERTIES 
IMPORTED_LINK_INTERFACE_LIBRARIES_RELEASE Library)

and it just has no effect. There is no trace of Library[D] in the 
generated files.
I'm using cmake 2.8.8 on windows for VS 9 2008.

Thanks,
Michele
