My program uses giblib and Imlib2 library and it is built with cmake.
It works perfectly in my computer but not in other's.
I guess the reason is I installed every library what my program needs but other's doesn't.
My goal is making standalone program. (don't need to install any other library addtionally)
What should I add in cmake file?

Try starting with this options in your root CMakeLists.txt:
set(BUILD_SHARED_LIBS OFF)
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -static")
BUILD_SHARED_LIBS is only needed if your project has its own libraries (add_library).
With the -static linker flag, you need static libs for ALL your additional libraries too! One common problem when static linking is to avoid circular dependencies.

I try to add the library spdlog to a dll (.so file). The spdlog is just a git submodule from the spdlog library. Looking at the documentation, it's recommended to use it as a static library. So i think i have a problem trying to compile it inside a .so file.
To get a clear view of what i'm doing, here is a pic of my system:
My root CMakeLists.txt is :
cmake_minimum_required(VERSION 3.23)
# set the project name
project(Test VERSION "0.1.0" LANGUAGES CXX)
configure_file(config/config.h.in config.h)
# specify the C++ standard
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)
set(CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17 -O3")
# Set location for .so files
set(CMAKE_INSTALL_PREFIX "${CMAKE_BINARY_DIR}")
# Set location for executables
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_BINARY_DIR}/bin)
add_subdirectory(Engine)
list(APPEND EXTRA_LIBS Engine)
add_subdirectory(Game)
target_link_libraries(Test PUBLIC ${EXTRA_LIBS})
target_include_directories(Test PUBLIC
"${PROJECT_BINARY_DIR}"
)
And inside the Engine folder:
message(STATUS "BUILD Engine shared library File")
add_subdirectory(spdlog)
add_library(Engine SHARED Log.cpp Log.h)
target_include_directories(Engine
INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}
)
target_link_libraries(Engine
spdlog
)
target_include_directories(Engine
INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}/spdlog/include
)
Inside the Game (not relevant at my opinion)
message(STATUS "BUILD .exe File")
# add the executable
add_executable(Test main.cpp)
But currently, if i try to use the spdlog inside my Log file, i have this cryptic error:
[build] /usr/bin/ld: spdlog/libspdlogd.a(spdlog.cpp.o): relocation R_X86_64_TPOFF32 against `_ZGVZN6spdlog7details2os9thread_idEvE3tid' can not be used when making a shared object; recompile with -fPIC
Does anyone have an idea?
Thanks to fabian in the comments, I add
set(CMAKE_POSITION_INDEPENDENT_CODE 1)
Just before adding the spdlog subdirectory and it just works fine.
I am new to C++ and have just started to use Cmake for linking the libraries to my project. I need to use a library:
https://github.com/Gnimuc/FastPD
Fortunately, I managed to build the library using Cmake (in my build there is no *.lib file at all), but I don't know how to link it to my project. I mean that I don't know how to add it to my cmakelists.txt :
(PS. I'm also using two other libraries ITK and VTK; but I can't link the above mentioned library to my project or main.cpp.)

Thanks in advance for your helps,
Assuming you installed the library and its header files, you can then search for the header files using find_path, and add the found path to the include directories. Then you can search for the library by using find_library, and add the library with the target_link_libraries command.
I tried both shared and static types for creation of the library. In the case of shared, no *.lib file was created, and in the case of static, my project couldn't link to the library. Therefore, in my project's CmakeLists.txt, I decided to add all the *.cpp and headers as libraries and then link them together (as I didn't know the dependency among them!!!), and finally, I linked them to my project. Perhaps it does not make sense but it works; hope it helps you:

I have a problem that in my project I have multiple libraries who all link eachother differently.
And then there is one executable that links to only one library.
Now there are two problems:
1) The linked libraries are not showing up in the librarian of the static libraries.
2) the librarires are all showing up at the executable.
So here is my project order
Game|- Engine|--Core|---Graphics|----Libpng|---Platform
so Graphic links Libpng
Core links Graphics and Platform
Engine links Core
Game links Engine
Utilities is an interface library so headers only
what happens is that all Additional dependencies are at Game
The librarian of Core, Engine and Graphic containts no additional dependencies.
This is the Root CMake

The other look the same.
I've tried PRIVATE instead of LINK_PRIVATE but the result is the same.
You can't link static libraries against each other and it is normal that they only showing up at the executable. Does your code not compiling?
For more information about static and dynamic libraries I suggest this article.
If you want to change the library type in cmake specify the add_lib command:
add_library(${LIB_NAME} ${LIB_TYPE} ${SOURCE})
# with ${LIB_TYPE} = STATIC or SHARED

I have cli wrapper function which i am trying to configure in cmake. After i generate the project with cmake the generated .proj file does not have the property of clr support is set to no common languaage runtime support. below is my cmake file

#ADD_EXECUTABLE(obliquePlane ${HEADERS} ${SOURCES})
ADD_LIBRARY(ObliquePlaneWrapper SHARED ${HEADERS} ${SOURCES})
TARGET_LINK_LIBRARIES(ObliquePlaneWrapper ${LINK_LIBRARIES} ${ITK_LIBRARIES})
I manually set this property in the All_build project and the corresponding .proj file. When i build the project it is searching for the ObliquePlaneWrapper.dll which it should be generating. Is this a problem because of some flag not set for common language runtime support
You can manually supply Compile Flags to specific sources to be compiled with specific flags. This includes \CLR for Visual C++. See example here.

for a project I need to create an executable that includes all the libraries that I used (opencv, cgal) in order to execute it on a computer that has not those libraries. Currently, this is my CMakeLists.txt (I use linux).
cmake_minimum_required(VERSION 2.8)
#set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -Wall")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -Wall -O2")

add_library(OpenCV STATIC IMPORTED)
add_library(CGAL STATIC IMPORTED COMPONENTS Core)
add_library(GMP STATIC IMPORTED)

find_library(GMP_LIBRARY gmp /usr/lib)
include(src)
include( ${CGAL_USE_FILE} )
include( CGAL_CreateSingleSourceCGALProgram )
set(EXECUTABLE_OUTPUT_PATH ../bin)
set(CMAKE_EXE_LINKER_FLAGS "-static-libgcc -static-libstdc++")
include_directories( src )
include_directories( ${OpenCV_INCLUDE_DIRS} )
file(GLOB_RECURSE nei_SRC "src/*.cpp")
add_executable( nei_segmentation ${nei_SRC})
target_link_libraries( nei_segmentation ${OpenCV_LIBS} ${GMP_LIBRARY})
In such a way only GMP and some other c++ libraries are included in my executable. My question is: How can I create a makefile in order to automatically including all the libraries in a static manner and creating only a "big" executable that contains all the libraries? Can you help me?
As global CMake settings, add these lines before add_executable, valid for gcc/clang:
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
set(BUILD_SHARED_LIBS OFF)
set(CMAKE_EXE_LINKER_FLAGS "-static")
On Modern CMake (3.x+ - target_link_libraries doc), you can apply the flag to specific targets, in this way:
target_link_libraries(your_target_name -static)
If you're using MSVC, you have to set the compiler and linker flags:
set(CMAKE_FIND_LIBRARY_SUFFIXES ".lib")
target_compile_options(your_target_name [PUBLIC|PRIVATE] /MT)
target_link_options(your_target_name [PUBLIC|PRIVATE] /INCREMENTAL:NO /NODEFAULTLIB:MSVCRT)
or alternatively also:
set(CMAKE_MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug>")
and if you are using MFC, you need to specify the flag to 1 see here:
set(CMAKE_MFC_FLAG 1)
Add these lines after add_executable(MyExec "main.c") (for example) :
target_link_libraries(MyExec PUBLIC "-static")
or before: link_libraries("-static")
