Catch::AssertionInfo& Issues Preventing Build

[jasonmeverett]

Using the CMAKE system, I have the following as my CMakeLists.txt file:

cmake_minimum_required(VERSION 3.10)
project(Modeller VERSION 0.1)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED True)

add_subdirectory(entityx)
add_executable(Modeller src/testing.cpp)
target_link_libraries(Modeller entityx)

I also have the entire entityx/ directory at the root of my project.

This is src/testing.cpp:

#include "entityx/entityx.h"

int main()
{
    entityx::EntityX ex;

    return 0;
}

Error output is as follows:

The errors continue on but all take the same form as the error seen in the last lines above.

What is going on here? It does look like the target is being built, but then not being linked properly? Any help is appreciated.

This is solved. Solution is CMAKE file below:

add_subdirectory(entityx)
find_library(entityx REQUIRED HINTS build/entityx)
add_subdirectory(pybind11)
pybind11_add_module(Modeller 
    src/world.cpp
    src/CMD.cpp
    src/sim.cpp
    src/output.cpp
    src/pyinterface.cpp
    src/integrator.cpp
    src/Modeller.cpp
    src/example1.cpp
    )
set_target_properties(entityx PROPERTIES POSITION_INDEPENDENT_CODE ON)
target_link_libraries(Modeller PRIVATE entityx)

target_include_directories(Modeller PUBLIC
    "${PROJECT_SOURCE_DIR}/eigen"
    "${PROJECT_SOURCE_DIR}/entityx"
    "${PROJECT_SOURCE_DIR}/pybind11/include"
    "${PROJECT_SOURCE_DIR}/include"
    )
