Linking C++ on Rust: undefined reference to `operator delete(void*)' and `__gxx_personality_v0', libstdc++ missing? - cmake

I'm trying to build a cpp cmake project and link to my Rust project.
cmake_minimum_required(VERSION 3.0)
set (CMAKE_CXX_STANDARD 17)
project(ZLMediaKit_LIB CXX)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17")
set(ENABLE_TESTS OFF FORCE)
option(ENABLE_TESTS OFF)
set(ENABLE_OPENSSL FALSE FORCE)
option(ENABLE_OPENSSL OFF)
add_subdirectory(ZLMediaKit)
add_library(libzlmediakit_cpp_interface STATIC interface.cpp)
target_include_directories(libzlmediakit_cpp_interface PUBLIC
.
${CMAKE_CURRENT_SOURCE_DIR}/ZLMediaKit/src
${CMAKE_CURRENT_SOURCE_DIR}/ZLMediaKit/3rdpart/ZLToolKit/src)
target_link_libraries(libzlmediakit_cpp_interface zlmediakit zltoolkit mpeg mov flv libstdc++)
install(TARGETS libzlmediakit_cpp_interface DESTINATION .)
Here's my build.rs:
extern crate cmake;
use cmake::Config;
fn main()
{
let dst = Config::new("zlmediakit_lib").build();
println!("cargo:rustc-link-search=native={}", dst.display());
println!("cargo:rustc-link-lib=static=libzlmediakit_cpp_interface");
}
But I'm getting undefined reference errors:

collect2: error: ld returned 1 exit status
I've researched and found some answers (Link error "undefined reference to `__gxx_personality_v0'" and g++) that old me to link against libstdc++. As you see, I'm already doing that.
If I try to compile the CMake project alone, it links sucessfully. However then I compile everything from the Rust side, it gives this error.

Undefined reference to klee when building s2e

I'm trying to start a new prject and build s2e in a new directory. But at arounf the 100% mark, it gives me an undefined reference error. The relevant part (imo) is this:

My directory structure is such:
|-s2e-env
|-s2e_projects
|-venv
I followed the steps from here: http://s2e.systems/docs/s2e-env.html I followed all the steps upto s2e build which is where this problem occurs.
For reference, the (truncated) output which I got from doing s2e build &> log:

I had the exact same error and solved it with:
sudo apt install gcc-9 g++-9
Also check to make sure clang selects the installed gcc-9 toolchain:
$ PATH_TO_S2E/install/bin/clang++ -v
...
Selected GCC installation: /usr/bin/../lib/gcc/x86_64-linux-gnu/9
...
As for why a compatible gcc toolchain is needed, even though clang is used to compile S2E:
Why clang selects a gcc installation?

in a CMakeLists.txt file in the protocol folder, im getting a

which should be in the libs folder and also is getting compiled beforehand.
As asked, more or less the full error part. which is at the moment mostly a repetition of static library dependency errors.

How do I use SFML with CMake FetchContent?

So I'd like to get the SFML from the git tag directly using CMake FetchContent. Most of the tutorial are not using this, so I don't really know what to do, I use imgui-sfml-fetchcontent for the reference.
My CMakeLists.txt
cmake_minimum_required(VERSION 3.10)
include(FetchContent)
project(2DComputerGraphics)
set(CMAKE_CXX_STANDARD 17)
# SFML
set(SFML_VERSION "2.5.1")
FetchContent_Declare(
SFML
GIT_REPOSITORY "https://github.com/SFML/SFML.git"
GIT_TAG "${SFML_VERSION}"
)
FetchContent_GetProperties(SFML)
if(NOT SFML_POPULATED)
FetchContent_Populate(SFML)
add_subdirectory(${SFML_SOURCE_DIR} ${SFML_BINARY_DIR})
#
# message("SFML_SOURCE_DIR: ${SFML_SOURCE_DIR}")
# message("SFML_BINARY_DIR: ${SFML_BINARY_DIR}")
endif()
set(SOURCE
"main.cpp"
)
#
# message("Source: ${SOURCE}")
add_executable(2DComputerGraphicsApp
"${SOURCE}"
)
target_include_directories(2DComputerGraphicsApp PRIVATE
"${SFML_INCLUDE_DIR}"
)
#
# message("SFML_INCLUDE_DIR: ${SFML_INCLUDE_DIR}")
target_link_libraries(2DComputerGraphicsApp
"${SFML_LIBRARIES}"
"${SFML_DEPENDENCIES}"
)
#
# message("SFML_LIBRARIES: ${SFML_LIBRARIES}")
# message("SFML_DEPENDENCIES: ${SFML_DEPENDENCIES}")
target_compile_options(2DComputerGraphicsApp PRIVATE -Wall)
And it gives me this error

I think it happen because I did not link the SFML correctly. How do I solve this?
The variables are wrong. https://cmake.org/cmake/help/v3.16/module/FetchContent.html states that <name> has to be lower case. Also squareskittles is right, you shouldn't use ${SFML_LIBRARIES} / ${SFML_INCLUDE_DIR}, this is only valid if the old FindSFML.cmake is used.

Cannot properly link the libraries in CMakeLists

I have some troubles with linking the source files (I have added them as Libraries in my CMakeLists) with my main file. Here is my CMakeLists:
cmake_minimum_required(VERSION 2.8.3)
project(ros_bridge)
set(${PROJECT_NAME}_CATKIN_COMPONENTS
nav_msgs
roscpp
sensor_msgs
std_msgs
)
add_compile_options(-std=c++14)
find_package(catkin REQUIRED COMPONENTS ${${PROJECT_NAME}_CATKIN_COMPONENTS})
find_package(RapidJSON REQUIRED)
catkin_package(
INCLUDE_DIRS
include
include/aws_iot_sdk
include/common
include/network
CATKIN_DEPENDS ${${PROJECT_NAME}_CATKIN_COMPONENTS}
)
include_directories(
include
include/aws_iot_sdk
${catkin_INCLUDE_DIRS}
)
## Libraries
add_library(ros_client src/ros_client.cpp)
add_library(ConfigCommon include/common/ConfigCommon.cpp)
add_library(OpenSSL include/network/OpenSSL/OpenSSLConnection.cpp)
add_library(WebSocket include/network/WebSocket/WebSocketConnection.cpp)
add_executable(ros_bridge_node src/main.cpp)
## Lib links
target_link_libraries(ros_client ConfigCommon ${catkin_LIBRARIES} ${RapidJSON_LIBRARIES} OpenSSL WebSocket)
target_link_libraries(ConfigCommon ${catkin_LIBRARIES} ${RapidJSON_LIBRARIES} OpenSSL WebSocket)
target_link_libraries(ros_bridge_node ${catkin_LIBRARIES} ros_client ConfigCommon OpenSSL WebSocket ${RapidJSON_LIBRARIES})
So when the compiler tries to link my main file (which is ros_bridge_node) I get the error with the linkage:
ros_client.cpp:(.text+0x605): undefined reference to `awsiotsdk::util::Logging::GetLogSystem()'
ros_client.cpp:(.text+0x66d): undefined reference to `awsiotsdk::ResponseHelper::ToString[abi:cxx11](awsiotsdk::ResponseCode)'

/home/abyl/master-wheel/devel/lib/libWebSocket.so: undefined reference to `BIO_set_flags'
/home/abyl/master-wheel/devel/lib/libWebSocket.so: undefined reference to `BIO_new'
So how can I properly link the libraries against my Main file?
EDIT:
I have set the object files of aws_iot_sdk like this:
set(${aws_sdk} /home/ren/aws-iot-device-sdk-cpp/build/CMakeFiles/aws-iot-sdk-cpp.dir/src)
set_source_files_properties(
${aws_sdk_path}
PROPERTIES
EXTERNAL_OBJECT true
GENERATED true
)
And tried to link that against my main file:
target_link_libraries(ros_bridge_node ros_client ConfigCommon Open WebSocket wslay ${RapidJSON_LIBRARIES} ${catkin_LIBRARIES} -lssl ${aws_sdk})
But still getting the same linkage problem. May be I am linking the object files wrong? (Now all the linkage problem is from the aws_iot_sdk)

I had a similar problem. I fix it by adding
find_library( GMP_LIB NAMES "gmp" PATHS ${CMAKE_LIBRARY_PATH} )
and add it to the target_link_libraries
