I am trying to cross compile a c++ project that uses openCV and a camera API for Raspberry Pi but I have the following linker error after the compilation finishes successfully: make[2]: No rule to make target '/opt/vc/lib/libmmal_core.so', needed by 'agv_car'. Stop. although the .so file is in an directory that is included in the search directories(see cmake file below)
CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)

INCLUDE_DIRECTORIES($ENV{HOME}/rpi/rootfs/opt/vc/include/interface/vcos/pthreads)

find_package(raspicam REQUIRED)
file(GLOB SOURCE_FILES src/*.cpp)
add_executable(agv_car ${SOURCE_FILES})
target_link_libraries(agv_car ${OpenCv_LIBS} ${raspicam_CV_LIBS})
And here is the tool chain cmake file:
SET(CMAKE_SYSTEM_NAME Linux)

SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
# Search for libraries and headers only in the target directories
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)

Any suggestions would be helpful, I have spent some time trying to figure it but without any success. "rpi/rootfs" is the location where I have copied the root file directory of the Raspberry Pi from the SD card.
EDIT
after doing the changes Tsyvarev suggested I get the following errors: `

I want to cross-compile c++ code for my raspberry-pi on my notebook (Ubuntu 18.04) and I spent hours and it still doesn't work.
I followed this little tutorial and it's working.
I want to link against the eclipse paho-mqtt-c++ lib, which I installed on my raspberry. I did rsync with my raspberry as in the tutorial, I now have a rootfs folder and there under rootfs/usr/local/include/ the header files for using the lib are stored and the lib itself is under rootfs/usr/local/lib.
My toolchain cmake file contains the following:
SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_C_COMPILER $ENV{HOME}/applications/raspberry-tools/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc)
SET(CMAKE_CXX_COMPILER $ENV{HOME}/applications/raspberry-tools/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++)
#SET(CMAKE_SYSROOT /home/manuelhoffmann/applications/raspberry-tools/rootfs)
SET(CMAKE_FIND_ROOT_PATH $ENV{HOME}/applications/raspberry-tools/rootfs)
#SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} --sysroot=${CMAKE_FIND_ROOT_PATH}")
SET(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} --sysroot=${CMAKE_FIND_ROOT_PATH}")
SET(CMAKE_MODULE_LINKER_FLAGS "${CMAKE_MODULE_LINKER_FLAGS} --sysroot=${CMAKE_FIND_ROOT_PATH}")
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)
#SET(CMAKE_LIBRARY_PATH /home/manuelhoffmann/applications/raspberry-tools/rootfs/usr/local/lib)
include_directories(${CMAKE_FIND_ROOT_PATH}/usr/local/include)

#link_directories(${CMAKE_FIND_ROOT_PATH}/usr/local/lib)
#find_library(${CMAKE_FIND_ROOT_PATH}/usr/local/lib)
add_definitions(-Wall -std=c11)
The include_directories was necessary so that it finds the headers and now it is compiling fine. But it still has a problem when linking, the output is:
raspberry-tools/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -pthread CMakeFiles/kg_iot_gateway.dir/gateway.cpp.o CMakeFiles/kg_iot_gateway.dir/MQTTClient.cpp.o CMakeFiles/kg_iot_gateway.dir/socket.cpp.o CMakeFiles/kg_iot_gateway.dir/snmessage/MessageGWInfo.cpp.o CMakeFiles/kg_iot_gateway.dir/snmessage/MessagePublish.cpp.o CMakeFiles/kg_iot_gateway.dir/snmessage/MQTTSNFlags.cpp.o CMakeFiles/kg_iot_gateway.dir/snmessage/MQTTSNMessage.cpp.o CMakeFiles/kg_iot_gateway.dir/snmessage/MQTTSNMessageHeader.cpp.o CMakeFiles/kg_iot_gateway.dir/snmessage/MQTTSNMessageVariablePart.cpp.o CMakeFiles/kg_iot_gateway.dir/main.cpp.o -o kg_iot_gateway -lpaho-mqttpp3

All commented lines didn't work or bring the desired result.
So how can I tell cmake to look for libs also in rootfs/usr/local/lib? What am I doing wrong?
Thanks for helping!
I'm trying to link a downloaded library called ArduinoJson to my project with CMake, but it seems that whenever i include the file it is missing, it will just ask for the next file its missing. I will end up with a lot of include lines which i think isnt the right way. I cant seem to find the correct syntax to include a libary in CMake

I would like to add 2 maybe 3 lines which include all the libraries i need for my ArduinoJson library
I'm trying to compile a c++ program that uses xlib with cmake. However, I'm having a problem including and linking xlib libraries in cmake file.
This is the error that I'm getting.
main.cpp:378: undefined reference to `XClearWindow'

And when I use just the command line to compile, it works just fine.
I use this command (g++ main.cpp -L/usr/X11R6/lib -lX11)
and this is my cmake file.
cmake_minimum_required(VERSION 3.6)
project(project1)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
link_directories(/usr/X11R6/lib)
include_directories(/usr/share/X11)
set(SOURCE_FILES main.cpp)
add_executable(project1 ${SOURCE_FILES})
In your case, you forgot to specify the libraries that cmake should use to link your application (target_link_libraries or link_libraries).
But, why not just let cmake find the required path, libraries and includes by itself? I suggest you to use find_package(X11). In your case, you can try:
cmake_minimum_required(VERSION 3.6)
project(project1)
set(CMAKE_CXX_STANDARD 11) # for c++11
find_package(X11 REQUIRED)
link_libraries(${X11_LIBRARIES})
include_directories(${X11_INCLUDE_DIR})
set(SOURCE_FILES main.cpp)
add_executable(project1 ${SOURCE_FILES})
I won't be able to explain why (if you have some idea, don't hesitate to comment my answer), but, in my case, I had to link X11 library using this command:
target_link_libraries( DisplayImage "-lX11" )
It works, at least, for the 3.5.1 version of cmake.
I have been struggling to find an answer to this question across Stackoverflow, at least one that I understand. I recently bought CLion and want to port an older project from Visual Studio over to it. But I have no idea how to link or add .lib files to my project. I need to link Xinput and DSound.
In Visual Studio I just added the headers and then added these to the top of my file
#pragma comment(lib, "XInput.lib")
#pragma comment(lib, "Dsound.lib")
I just have absolutely no idea how to link to those libs using CMake as I am a complete beginner with it.
Any Help would be gladly appreciated
This is my current CMake file
cmake_minimum_required(VERSION 3.3)

UPDATE
cmake_minimum_required(VERSION 3.3)

Simply add these after your CMakeLists.txt
