[hatari-devel] compilation failing for cigwin on cirrus CI

[Nicolas Pomarède <npomarede@xxxxxxxxxxxx>]

Hi

somewhere around libSDL2_2.0_0 went from 2.0.7-1 to 2.28.2-1 and since 
then the compilation is failing for the cigwin version :

https://cirrus-ci.com/github/hatari/hatari

-- Configuring done
CMake Error at src/CMakeLists.txt:179 (target_link_libraries):
  Target "hatari" links to:
    SDL2::SDL2
  but the target was not found.  Possible reasons include:
    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

I guess some files need to be updated to help cmake finding the library ?
