I think the error is actually this (abridged):

-- SDL2_INCLUDE_DIR is SDL2_INCLUDE_DIR-NOTFOUND
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
/build/widelands-20/src/SDL2_INCLUDE_DIR
   used as include directory in directory /build/widelands-20/src
-- Configuring incomplete, errors occurred!

The trigger to breaking cmake/Modules/FindSDL2.cmake in widelands is
libsdl2 2.0.10+dfsg1-2, it seems. The attached patch fixes this FTBFS.

Markus, you have made team uploads of widelands before. I wonder if you
could make an upload that adds the patch?
