Hi,

During `xeus` configure step I get the following error:

```auto
  -- Detecting CXX compile features
  -- Detecting CXX compile features - done
  -- xeus version: v2.3.1
  -- xeus binary version: v7.1.1

  CMake Error in CMakeLists.txt:
    Imported target "OpenSSL::Crypto" includes non-existent path

      "C:/C/r/OpenSSL-install/$(Configuration)/include"

    in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include:

    * The path was deleted, renamed, or moved to another location.

    * An install or uninstall procedure did not complete successfully.

    * The installation package was faulty and references files it does not
    provide.

```

That happens because `$(Configuration)` is unwrapped only at buildtime (or at generation time I don’t remember).  
Thus with multiconfig generators OpenSSL includes non-existent path at configure time.  
`xeus` tries to link to OpenSSL` and gives me this error.

I sligghtly modified [External\_OpenSSL.cmake](https://github.com/Slicer/Slicer/pull/6414/files) in a way that if the developper explicitely pass `-DCMAKE_BUILD_TYPE=smth` then the mentioned error doesn’t arise anymore.

I know that somebody already tried to bundle SlicerJupyter with SlicerCAT. If somebody encountered the same problem please give some hints.
