CMake Error at CMakeLists.txt (target_link_libraries)

I have a problem with CMake. I have wrote a CMakeList.txt file. But when I run it with Cmake I got a strange error "CMake Error at CMakeLists.txt:17 (target_link_libraries): Cannot specify link libraries for target "debug" which is not built by this project.".

Is it possible to create a Cmake file that can build a project file for Debug and Release mode at the same time? Or is there a simple way to fix this error?

My CMakeLists.txt looks like this:

  cmake_minimum_required (VERSION 2.8)

project (SimuVille)

# Import required CMake files
set (CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake/Modules")

file(GLOB_RECURSE files
    "*.cpp"
)

add_executable(debug ${files})

# Find the find Modules
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})

#Find any version 2.X of SFML
#See the FindSFML.cmake file for additional details and instructions
find_package(SFML 2 REQUIRED system window graphics network audio)
if(SFML_FOUND)
    include_directories(${SFML_INCLUDE_DIR})
    target_link_libraries(${EXECUTABLE_NAME} ${SFML_LIBRARIES})
endif()


#Find SfeMovie
find_package(sfeMovie REQUIRED)
if(SFEMOVIE_FOUND)
    include_directories(${SFEMOVIE_INCLUDE_DIR})
    target_link_libraries(${EXECUTABLE_NAME} ${SFEMOVIE_LIBRARY})
endif()

#Find Assimp
find_package(ASSIMP REQUIRED)
if(ASSIMP_FOUND)
    include_directories(${ASSIMP_INCLUDE_DIR})
    target_link_libraries(${EXECUTABLE_NAME} ${ASSIMP_LIBRARY})
endif()

#Find DevIL
find_package(DevIL REQUIRED)
if(IL_FOUND)
    include_directories(${IL_INCLUDE_DIR})
    target_link_libraries(${EXECUTABLE_NAME} ${IL_LIBRARY})
    target_link_libraries(${EXECUTABLE_NAME} ${ILU_LIBRARY})
    target_link_libraries(${EXECUTABLE_NAME} ${ILUT_LIBRARY})
endif()

#Find opengl libs
find_package(OpenGL REQUIRED)
include_directories(${OpenGL_INCLUDE_DIRS})
link_directories(${OpenGL_LIBRARY_DIRS})
add_definitions(${OpenGL_DEFINITIONS})
if(NOT OPENGL_FOUND)
    message(ERROR " OPENGL not found!")
endif(NOT OPENGL_FOUND)

#file(GLOB_RECURSE hfiles
#    "*.h"
#)

#add_executable(SimuVille ${hfiles})


LINK_DIRECTORIES(${CMAKE_SOURCE_DIR}/Game)
LINK_DIRECTORIES(${CMAKE_SOURCE_DIR}/GameEngine)
LINK_DIRECTORIES(${CMAKE_SOURCE_DIR}/GameEngine/SfmlObject)
LINK_DIRECTORIES(${CMAKE_SOURCE_DIR}/GameEngine/Camera)
LINK_DIRECTORIES(${CMAKE_SOURCE_DIR}/GameEngine/OpenglObject)
LINK_DIRECTORIES(${CMAKE_SOURCE_DIR}/GameEngine/Playable)

Edit: Added new source code.

I have the same problem. I am just learning C++, have always used python. Trying to add libraries in Clion- installed through Vcpkg and copied the example straight from the JetBrains website...

cmake_minimum_required(VERSION 3.28)
project(Test)
add_executable(Test main.cpp)
find_package(PNG REQUIRED)
include_directories(${PNG_INCLUDE_DIR})
target_link_libraries(main PRIVATE ${PNG_LIBRARY})
set(CMAKE_CXX_STANDARD 17)

but I got :

CMake Error at CMakeLists.txt:6 (target_link_libraries):
  Cannot specify link libraries for target "main" which is not built by this
  project.

So, I changed the order and made sure to add everything underneath...

cmake_minimum_required(VERSION 3.28)
project(main)

set(CMAKE_CXX_STANDARD 17)

add_executable(main main.cpp)
find_package(PNG REQUIRED)
include_directories(${PNG_INCLUDE_DIR})
target_link_libraries(main PRIVATE ${PNG_LIBRARY})

and it worked.

Looks like your CMakeLists.txt doesn't contain either of two lines (which depends you are creating a library or a executable) 

add_library(debug <files Name>)

OR

add_executable(debug <files Name>)

If you have these lines in your file, place it before target_link_libraries ()
