Audio / SFML won't load audio files on Windows but works fine on Linux

Hello,

I am currently developping a project of a 3D video game in C++. I want to use the SFML Audio module to manage musics and sounds in my game. I use CMake to compile under both Linux and Windows.

Under Linux (compiles with c++ through generated Makefile), everything works perfectly fine, but when I try to launch under Windows (compiles with MSVC in a generated VS 16 (2019) solution), the SFML won't load the music anymore (more specifically, the loadFromFile function fails).

Here is the test code sample I use (directly in the main, which is just a big code sample for testing all my libraries so I just give here he SFML Audio related part):

    sf::SoundBuffer soundBuffer;          //Tried with a sf::SoundBuffer + sf::Sound
    sf::Sound sound;
    if (!soundBuffer.loadFromFile("assets/music/test_music.ogg")) //      <-- fails here
        return -2;
    sound.setBuffer(soundBuffer);
    sound.play();

    /*                          Also tried with sf::Music, with this piece of code, fails exactly at the same function call
    sf::Music music;
    if (!music.openFromFile("assets/music/test_music.ogg")) //          <-- fails here
        return -3;
    music.play();*/
 

This code runs fine under Linux, but for some reason not under Windows.
Here is what I already checked:
    - The path is right (some other assets are accessed by other libs, so I know the assets directory is accessible, and I quintuple checked the rest of the path)
    - The OGG Vorbis file is not corrupted (plays well in any media player both on Linux and Windows + recorded and encoded it myself in Audacity.
    - The SFML dependencies are correctly loaded (.dll is in the build directory, .lib is linked in CMake, headers are included correctly.)
    - I tried using the sfml-audio-d-2.dll instead of the smfl-audio-2.dll, just in case. Doesn't work either.
    - The argument format (I checked there wasn't a problem of `WCHAR *` instead of `char *`)

I use the 64 bits library, because VS wouldn't accept the 32 bits one (saying I am compiling the project for 64 bits platforms -- which is intended). I switched without really thinking about it since the game is not meant to be played on 32 bits devices, could this cause problems?

Also, I am new to programming in C++ in Windows, so there might be something I did wrong in that aspect.

Thank you in advance for any help !
