Seeking Help with C2065 Error in C++ Code

Thank you for your response. I used cmake to build this code. Here is my cmakelists:

cmake_minimum_required(VERSION 3.12.0)

project(mainOcct)

# Set the directory where OpenCASCADE is installed
set(OpenCASCADE_DIR "C:/Users/95439/source/repos/arungoooo112/OCCT/out/install/x64-Debug/cmake")

# Try to find OpenCASCADE package
find_package(OpenCASCADE REQUIRED)

# Check if OpenCASCADE is found
if(OpenCASCADE_FOUND)
    message(STATUS "OpenCASCADE found!")
    message(STATUS "OpenCASCADE_INCLUDE_DIRS: ${OpenCASCADE_INCLUDE_DIRS}")
    message(STATUS "OpenCASCADE_LIBRARIES: ${OpenCASCADE_LIBRARIES}")
else()
    # If OpenCASCADE is not found, print error message and terminate CMake configuration
    message(FATAL_ERROR "OpenCASCADE not found!")
endif()

# Add an executable target
add_executable(mainOcct main.cpp)

# Link OpenCASCADE libraries to the executable
target_link_libraries(mainOcct PRIVATE ${OpenCASCADE_LIBRARIES})

# Include OpenCASCADE header files
target_include_directories(mainOcct PRIVATE ${OpenCASCADE_INCLUDE_DIRS})

message(STATUS "CMake compiler: ${CMAKE_CXX_COMPILER}")
message(STATUS "CMake compiler ID: ${CMAKE_CXX_COMPILER_ID}")
message(STATUS "CMake compiler version: ${CMAKE_CXX_COMPILER_VERSION}")
message(STATUS "CMake system name: ${CMAKE_SYSTEM_NAME}")

output:
