the is a lot lines sorry my main Cmake codes

cmake_minimum_required(VERSION 3.27)
project(SFML)

set(CMAKE_CXX_STANDARD 17)

add_executable(SFML main.cpp)

set(SFML_STATIC_LIBRARIES TRUE)
set(SFML_DIR C:/SFML/lib/cmake/SFML)
find_package(SFML COMPONENTS system window graphics audio network REQUIRED)

include_directories(C:/SFML/include/SFML)
target_link_libraries(SFML sfml-system sfml-window sfml-graphics sfml-audio)
add_executable(Dynamic_2 ${CMAKE_CURRENT_SOURCE_DIR}/Main.cpp)
target_include_directories(
        SFML
        PUBLIC
        ${CMAKE_CURRENT_SOURCE_DIR}/include
)

now there is my imgui file cmake codes

include(FetchContent)

set(SFML_VERSION 2.6.1)
set(IMGUI_VERSION 1.87)
#set(IMGUI_SFML_VERSION 2.6)

# It's nice to get stripped-down release zips instead of cloning
# a repo and checking out a tag
FetchContent_Declare(
        SFML
        URL "https://github.com/SFML/SFML/archive/${SFML_VERSION}.zip"
)

FetchContent_Declare(
        imgui
        URL "https://github.com/ocornut/imgui/archive/v${IMGUI_VERSION}.zip"
)

# Or by tag...
FetchContent_Declare(
        imgui-sfml
        GIT_REPOSITORY https://github.com/SFML/imgui-sfml.git
        GIT_TAG        2.6.x
        # GIT_COMMIT 5f54b69b6aee18db846c81633f86f78c2586dded
        # ^ or like this - sometimes it's better because FetchContent won't look
        # into remote to see if branch head was updated or not - good for stable
        # tags like 'vX.X' corresponding to releases
)

## finally, let's build

# SFML
option(SFML_BUILD_AUDIO "Build audio" OFF)
option(SFML_BUILD_NETWORK "Build network" OFF)
FetchContent_MakeAvailable(sfml)

# Dear ImGui
FetchContent_MakeAvailable(ImGui)

# ImGui-SFML
set(ImGui)
option(ImGui_SFML_FIND_SFML "Use find_package to find SFML" OFF)
option(ImGui_SFML_ImGui_DEMO "Build imgui_demo.cpp" ON)

FetchContent_MakeAvailable(imgui-sfml)
