Why does my code generated from MATLAB Coder fail to compile because of missing function definitions for "omp_init_nest_lock" and "omp_destroy_nest_lock"?

Why does my code generated from MATLAB Coder fail to compile because of missing function definitions for "omp_init_nest_lock" and "omp_destroy_nest_lock"?
I am trying to compile the code on a Linux operating system and it fails because the compiler cannot find definitions for the mentioned functions. I do not know why these functions are appear in my code. I also noticed that the same code compiles on a different computer with a Windows operating system using Microsoft Visual Studio.

This issue is typically encountered if the Linux computer on which the code is being compiled has an outdated compiler. The functions "omp_init_nest_lock" and "omp_destroy_nest_lock" are implementations of "OpenMP" specifications and they should be provided by the compiler. On a Linux computer, installing the recommended version of the GCC compiler should resolve this issue.

If you use the CMake tool to compile, then it should link to the OpenMP library. Add the following example to CMakeLists.txt.
FIND_PACKAGE( OpenMP REQUIRED)
if(OPENMP_FOUND)
message("OPENMP FOUND")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
endif()
