I want to include assimp to my project using CMake. I have Ubuntu 14.04 LTE and QTCreator.
Project contain of main.cpp and linked libraries stored in libs directory.
Main CMakeLists.txt
cmake_minimum_required(VERSION 2.6)
project(test)
find_package(OpenGL REQUIRED)
# libs contain external libaries
add_subdirectory (libs)
include_directories(
libs/glfw-3.0.4/include
libs/assimp-3.1.1/include/
)
set(allLibs
${GLFW_LIBRARIES}
${OPENGL_LIBRARY}
GLEW_LIB
assimp
)
add_executable(test
main/main.cpp
)
target_link_libraries(Manipulator glfw assimp ${allLibs} )
CMakeList.txt inside libs directory
### GLFW ###
add_subdirectory (glfw-3.0.4)
include_directories(
glfw-3.0.4/include/GLFW/
glew-1.11.0/include/
assimp-3.1.1/include/
)
set(OPENGL_LIBRARY
-lGL -lGLU -lXrandr -lXext -lX11 -lrt
${CMAKE_DL_LIBS}
${GLFW_LIBRARIES}
)
### GLEW ###
set(GLEW_SOURCE
glew-1.11.0/src/glew.c
)
add_library( GLEW_LIB STATIC
${GLEW_SOURCE}
)
target_link_libraries(GLEW_LIB
${OPENGL_LIBRARY}
)
### ASSIMP ###
# Zlib
add_subdirectory( assimp-3.1.1/contrib/zlib )
# Boost workaround
include_directories( assimp-3.1.1/code/BoostWorkaround )
add_definitions( -DASSIMP_BUILD_BOOST_WORKAROUND )
# Compile AssImp
add_subdirectory( assimp-3.1.1/code )
And I receive following error.
CMake Error at libs/assimp-3.1.1/code/CMakeLists.txt:725 (INSTALL):
install TARGETS given no ARCHIVE DESTINATION for static library target
"assimp".
This point's me to this
INSTALL( TARGETS assimp # 725 line
LIBRARY DESTINATION ${ASSIMP_LIB_INSTALL_DIR}
ARCHIVE DESTINATION ${ASSIMP_LIB_INSTALL_DIR}
RUNTIME DESTINATION ${ASSIMP_BIN_INSTALL_DIR}

How to correctly link this library?
This is a CMakeList.txt that I use to build my project.
All external libraries were stored in libs directory. Main file was stored in main directory.
cmake_minimum_required (VERSION 2.6)

)
add_executable (openGL main/main.cpp
Source/vertexShader.vs
Source/fragmentShader.fs
)
target_link_libraries(openGL common assimp GLEW glfw ${GLFW_LIBRARIES})
CMakelist.txt from Common looks like this:
add_library(common model.cpp)
This should work on Ubuntu 14.04. If some libraries are missing try to follow steps from this tutorial tutorial

did I miss somethings?
if I replace Qt${QT_VERSION_MAJOR}::network to Qt${QT_VERSION_MAJOR}::Core or Gui , it works.
and also fail with Qt${QT_VERSION_MAJOR}::Multimedia.
If I remove Qt${QT_VERSION_MAJOR}::network, I will get a header file lost error.

I tried to used https://github.com/julianxhokaxhiu/SteamworksSDKCI to use steam api on a simple SFML application (helloworld).
I wanted to use cmake to learn it, but I am struggling to understand how the provided CMakeLists and Find*.cmake file are expected to be used.
Currently, I have modified the CMakeLists to change the INSTALL_DIR
INSTALL_DIR "${CMAKE_BINARY_DIR}/../../vendor"
and my CMakeLists is :
cmake_minimum_required(VERSION 3.19)
project(SfmlWithCMake VERSION 1.0)
include(FetchContent)
set (CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH};${CMAKE_CURRENT_SOURCE_DIR}/cmake_steam")
# Configure external project
file(MAKE_DIRECTORY ${CMAKE_BINARY_DIR}/cmake_steam)
execute_process(
COMMAND ${CMAKE_COMMAND} ${CMAKE_SOURCE_DIR}/cmake_steam
WORKING_DIRECTORY ${CMAKE_BINARY_DIR}/cmake_steam
)
# Build external project
execute_process(
COMMAND ${CMAKE_COMMAND} --build ${CMAKE_BINARY_DIR}/cmake_steam
)
set(BUILD_SHARED_LIBS OFF)

)
FetchContent_MakeAvailable(SFML)
find_package(STEAMWORKSSDK REQUIRED)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED true)
# Generate config.h
configure_file(config.h.in config.h)
add_executable(
SfmlWithCMake
main.cpp
)
get_target_property(STEAMSDK STEAMWORKSSDK::STEAMWORKSSDK INCLUDE_DIRECTORIES)
target_include_directories(
SfmlWithCMake

"${STEAMSDK}"
)
target_link_libraries(
SfmlWithCMake
sfml-graphics
STEAMWORKSSDK::STEAMWORKSSDK
-static gcc stdc++ winpthread -dynamic
)
install(TARGETS SfmlWithCMake DESTINATION bin)
How to get include directories?
I do not succeed to add the steam include to the target_include_directories.
Here the ${STEAMSDK} is my last attempt to get the directory.
If I replace this by ${PROJECT_BINARY_DIR}/vendor/include, everything works.
Also, why does the SFML include are automatically added to my target include directories and not the steam one?
Am I using the Find*.cmake file the right way?
I understood that ExternalProject_Add was performed at build time and thus, as the find_package is needed at configue time, I added the two "execute_process". But, the readme on github only says to do the find package and add the target to target_link_libraries...
Thanks.
when building a project stucture like following:
LinearAlgebra
|---HEADER
|-----|---Linear.h
|---SRC
|-----|---Linear.cpp
|---TEST
|-----|---hello_test.cc
here is my CMakeList.txt:

)
target_link_libraries(
hello_test
gtest_main
LA_HEADER
LA_SRC
)
include(GoogleTest)
gtest_discover_tests(hello_test)
it works fine with cmake -S . -B build, but when it comes to cmake --build build following error occured:
Undefined symbols for architecture x86_64:
"Linear::Linear()", referenced from:
HelloTest_BasicAssertions_Test::TestBody() in hello_test.cc.o
it seems something wrong with my cmake file that didn't tell Linear.h where Linear.cpp located. So how to fix it ?? thanks for your help...
seems i misunderstand add_library, change three lines and it works out:
cmake_minimum_required(VERSION 3.10)
project(LinearAlgebra )
include_directories(header) # include_directories instead of add_library for .h files
add_library(LA_LIB src/Linear.cpp) # use add_library for .cpp files only!!!
set(CMAKE_CXX_STANDARD 11)
include(FetchContent)
FetchContent_Declare(
googletest
URL https://github.com/google/googletest/archive/609281088cfefc76f9d0ce82e1ff6c30cc3591e5.zip
)
# For Windows: Prevent overriding the parent project's compiler/linker settings
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)
enable_testing()
add_executable(
hello_test
test/hello_test.cc
)
target_link_libraries(
hello_test
gtest_main
LA_LIB # link LA_LIB only..
)
include(GoogleTest)
gtest_discover_tests(hello_test)
leave it here for anyone have the same requirements.
I have compiled and installed with CMake the library SDL_bgi to a custom prefix /custom/prefix/. This library uses SDL2.
Now I want to use it in another project with the structure below but I get a linker error when I compile with make:
/usr/bin/c++ CMakeFiles/test.dir/test.cpp.o -o test -Wl,-rpath,/custom/prefix/lib: /custom/prefix/lib/libSDL_bgi.so
/usr/bin/ld: /custom/prefix/lib/libSDL_bgi.so: undefined reference to `SDL_DestroyWindow'
/usr/bin/ld: /custom/prefix/lib/libSDL_bgi.so: undefined reference to `SDL_CreateRenderer'
I have also written the file cmake/modules/FindSDL_bgi.cmake so that may be wrong as well.
If I compile with the following command I can compile correctly:
g++ test.cpp -I . -lSDL_bgi -lSDL2 -I /custom/prefix/include/ -L /custom/prefix/lib/
What am I doing wrongly?

What I was missing is to link to SDL2 with find_package(SDL2 REQUIRED) and link to SDL2::SDL2. (I did try to link to ${SDL2_LIBRARIES} but the syntax is different now). Thanks to #KamilCuk to point me to the right direction.
EDIT:
I changed the FindBGI_sdl.cmake module in order to search for the dependencies (SDL2) and link against them using the INTERFACE keyword. In this way the target test can link only against SDL_bgi and have the dependencies resolved automatically.
