CMAKE build gui application with MinGW

I want to build gui application with SDL2. I link SDL2 libraries(libSDL2.dll.a and libSDL2main.a) but I don't know how a can apply -mwindows flag to my application. Without him .exe file of my application doesn't show window (executing have not any effect). I use MinGW-w64 my OS is Windows 10. In command line I can do this like here (see section B). How I can apply this flag with usage cmake? Console application works fine.

I try next variant but it doesn't work.

cmake -G "MinGW Makefiles" -D CMAKE_C_COMPILER=gcc -D CMAKE_CXX_COMPILER=g++ -D CMAKE_EXE_LINKER_FLAGS="-mwindows"
cmake -G "MinGW Makefiles" -D CMAKE_C_COMPILER=gcc -D CMAKE_CXX_COMPILER=g++ -D CMAKE_CXX_FLAGS="-mwindows"

Also in CMakeLists.txt I try do like this

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mwindows")

I basically copy-pasted the stuff, which CLion executes in the command line, and it worked:

$ cmake DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - MinGW Makefiles" ../

$ cmake --build ./ --target target_name -j 6
[ 50%] Building CXX object CMakeFiles/target_name.dir/main.cpp.obj
[100%] Linking CXX executable target_name.exe
[100%] Built target tree_traverse

After this the executable target_name.exe appeared in the directory.

You can pass WIN32 argument to add_executable and CMake will do this for you:

add_executable(target_name WIN32 ${sources})
