Encountering challenges when integrating cvxpygen into existing projects.

I'm having difficulty integrating cvxpygen into my existing project. I'm unsure how to utilize the generated code in my established project.

The compiler complains about missing files. I suspect the issue lies in my CMakeLists.txt file:

CMake

cmake_minimum_required(VERSION 3.0.0)
project(mpc)

include(CTest)
enable_testing()

set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
include(CPack)

add_subdirectory(mpc-EST)
include_directories(include ${cpg_include})

add_executable(mpc main.c ${cpg_head} ${cpg_src})

My main.c file is simply meant to print the objective function value to verify the code's functionality:

C

#include <stdio.h>
#include "cpg_workspace.h"
#include "cpg_solve.h"

int main() {
  printf("Hello, World!\n");

  // Solve the problem instance
  cpg_solve();

  // Print objective function value
  printf("obj = %f\n", CPG_Result.info->obj_val);

  return 0;
}

Thank you for your assistance.

I resolved the issue by adding the -lm flag to the end of the /home/vboxuser/Documents/projetos_C/C/mpc/build/CMakeFiles/mpc.dir/link.txt file. However, I'm wondering if there's a way to automate this process.

-lm should be automatically added, see this CMake instruction. If the above persists, you might want to add

set (CMAKE_C_STANDARD_LIBRARIES "${CMAKE_C_STANDARD_LIBRARIES} -lm")

to your top-level CMakeLists.txt.
