Since You don’t select any artifacts, the Group has no effect. You probably want to use the Properties item (which works in modules as well. The limitation is that only one Properties item should write the same module property at a time (mutual exclusive). But that seems to be the case in your example.

Thanks!

Properties seems to be exactly what I want.

Here what I have now:
    StaticLibrary {
         files: ["date/include/date/*.h", "date/src/*.cpp"]
         name: "date"

         Depends { name: "cpp" }

         cpp.cxxLanguageVersion: "c++17"
         cpp.defines: ["HAS_REMOTE_API=0","AUTO_DOWNLOAD=0","INSTALL=."]
         cpp.includePaths: ["date/include"]

         Export {
             Depends { name: "cpp" }

             cpp.defines: product.cpp.defines
             cpp.includePaths: ["date/include"]

             Properties {
                 condition: qbs.toolchain.contains("mingw")

                 cpp.dynamicLibraries: ["pthread", "ole32"]
             }
         }
     }
