On windows platform we use cmake to generate VS projects, which have a total of 4 configuration modes: Debug, DebugEditor, Release, ReleaseEditor. now we have a new requirement, some modules are compiled as static libraries in Debug, Release mode, and as dynamic libraries in DebugEditor , ReleaseEditor mode as dynamic libraries.  
I’m using the following to set this up, but cmake can’t resolve it  
add\_library(Target $\<$CONFIG:Debug\>:STATIC\> “”)  
add\_library(Target $\<$CONFIG:DebugEditor\>:SHARED\> “”)

That argument to `add_library` does not support generator expressions. There’s no way to make a single target a different library type between configurations in a multi-config generator (such as Visual Studio); you’ll need to make two targets and select between them using generator expressions in the `target_link_libraries` calls (potentially made easier by an `INTERFACE` target that does this that can then be used directly).
