Ok, so I just tested you proposal. What I did:

- launched CMake,
- selected MINGW,
- configured a few variables (QT_QMAKE_EXECUTABLE, SDLIMAGE_INCLUDE_DIR,
SDLIMAGE_LIBRARY, SDL_INCLUDE_DIR, SDLMAIN_LIBRARY).
- generated the makefiles.

- click on start menu, and click on the launcher.
- launched "cmd" (I suppose that this is what you called Windows CLI)
- went to the directory
- launched "mingw32-make.exe"

And the error is the same as before. The "build.make" is the same as before
(I copied the linking part at the end of this mail).
Any idea?

I would like to check the value of the variables in the FindSDL.cmake (like
"MINGW"...) when I try to compile
my program. Is this possible?

 Can the problem be relevant to the fact that I am using the MINGW version
coming with Qt ?

Currently, I suppose that the first issue is not related to that, as even
with
MINGW it does not work...

Any idea?



the build.make:

# External object files for target bloodybeard
bloodybeard_EXTERNAL_OBJECTS =

bloodybeard.exe: CMakeFiles/bloodybeard.dir/main.obj
bloodybeard.exe: CMakeFiles/bloodybeard.dir/qGameEngine.obj
bloodybeard.exe: CMakeFiles/bloodybeard.dir/moc_qGameEngine.obj
bloodybeard.exe: lib/SDL_image.lib
bloodybeard.exe: lib/libSDLmain.a
bloodybeard.exe: C:/Qt/4.2.1/lib/libQtCore4.a
bloodybeard.exe: CMakeFiles/bloodybeard.dir/build.make
 @$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --red --bold
