RAYGUI : Undefined Reference and Double Defined Errors

[Universal-Flare]

Please, before submitting a new issue verify and check:

• [yes] I tested it on latest raylib version from master branch
• [yes] I checked there is no similar issue already reported
• [yes] I checked the documentation on the wiki
• [yes] My code has no errors or misuse of raylib

Issue description

It shows the error of Double Definitions which are defined in both raylib and raygui.
Without #define RAYGUI_IMPLEMENTATION at the top of the code, it shows an undefined reference error when run.

Environment

OS: Windows 11
OpenGL: Same from Raylib Default
Build System: Meson

Code Example

#include "raylib.h"

#define RAYGUI_IMPLEMENTATION
#include "raygui.h"

int main() {

    int screenWidth = 800;
    int screenHeight = 450;

    InitWindow(screenWidth, screenHeight, "");
    SetTargetFPS(60);

    bool BOXActive = true;

    Rectangle layoutRecs[1] = {
        (Rectangle){ 352, 64, 512, 408 },
    };

    while (!WindowShouldClose()) {

            ClearBackground(GetColor(GuiGetStyle(DEFAULT, BACKGROUND_COLOR)));

            if (BOXActive) {
                BOXActive = !GuiWindowBox(layoutRecs[0], "BOX_NAME");
            }

        EndDrawing();
    }

    CloseWindow();
};

Raylib Works perfectly fine with meson as I am using the CMake Module

sorry, accidentally clicked the wrong button

As i was saying, the raygui.h file for that code in my project does not work and give those errors.
I thought it was because of the first inititalisation of the functions but i was wrong

@Universal-Flare I'm afraid I can't reproduce, it could be related to the build system used.
