Problema con CMake ..

Buen día, podrian ayudarme por favor. Cuando ingreso cmake … me muestra lo siguiente:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 2.8.12 will be removed from a future version of
CMake.

Update the VERSION argument value or use a … suffix to tell
CMake that the project does not need compatibility with older versions.

CMake Warning at CMakeLists.txt:79 (find_package):
By not providing “FindSDL2.cmake” in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by “SDL2”, but
CMake did not find one.

Could not find a package configuration file provided by “SDL2” with any of
the following names:

SDL2Config.cmake
sdl2-config.cmake

Add the installation prefix of “SDL2” to CMAKE_PREFIX_PATH or set
“SDL2_DIR” to a directory containing one of the above files. If “SDL2”
provides a separate development package or SDK, be sure it has been
installed.

– Could NOT find FFTW (missing: FFTW_LIBRARIES FFTW_INCLUDE_DIRS)
CMake Warning at CMakeLists.txt:86 (message):
Unable to find SDL2 library. It is either not installed or CMake cannot
find it. In the latter case, setting the USE_FINDSDL2 variable might help:

 $ cmake -D USE_FINDSDL2 ..

CMake Error at CMakeLists.txt:91 (message):
Aborting

– Configuring incomplete, errors occurred!

Corrección, ahora me sale solo esto:
