[BUG]undefined reference to `WinMain'

[Thomas-mci-21]

Problem Description:
I'm working on a C++ project using CUDA and OptiX in VSCode with MinGW as the compiler. The goal is to create a console application. However, during the compilation process (I used make), I'm encountering the following linker error:

This error indicates that the linker is looking for an entry point named WinMain, but I have defined main as the entry point in main.cpp.

This is my Makefile (sorry for Chinese):

And these are all my codebase:

What I've Tried:
Confirmed the main function is used as the entry point:
In main.cpp, the entry point is correctly defined as int main(), not WinMain.
Used -mconsole in the Makefile:
I’ve set the -mconsole flag in the Makefile to ensure the program is compiled as a console application (not a GUI app).
CXXFLAGS = -std=c++17 -O2 -Wall -mconsole
Set the entry point to main with -Wl,--entry=main:
I explicitly set the entry point to main in the linker flags.
LDFLAGS = -L$(LIB_PATH) -L$(LIB_PATH_CUDA) -lcudart -lcuda -lcufft -Wl,--entry=main -mconsole
Checked linker error:
The error is still undefined reference to WinMain, meaning the linker is trying to find WinMain instead of main.
Tried removing -Wl,--entry=main:
I removed the -Wl,--entry=main flag, but the problem persists.

How can I solve this? Thanks for any help!
