That was an unrelated thing. I already fixed in another PR. |

Basically, libretro official binaries are stuck in a very old build.
We are trying to update it to the newest version at: libretro#28 @RobLoach
I was able to compile and build for all the systems, but then in the last one (emscripten), I noticed a thing: There are many systems with
-DLIBRETRO_STATIC=ONbuild pipelines expecting a single.astatic file as the output ofcmake --build.Like in: GameCube, 3DS, Wii, WiiU and Emscripten.
Currently, after building for those systems, I get many files. like:
and:
I noticed the problem because the
emscriptenpipeline has a build step using the .bc file, and I was getting:So I used the Antigravity editor with Gemini, and got it to do these changes to libretro.cmake
With these changes, it compiles for all those systems. I can attach the dockerfile for each system if requested. (I'm not attaching to not make this much longer.)
Anyway, I don't know if this is the appropriated way to fix this. But this is what I got.
