Hi There, So, I’m a web-dev by trade, with limited Native App Development experience, dipping my toes into the world of CPP, Java, Native Android etc… so please forgive any lack of simple understanding on display here… I’m trying to add libleiasdk.so to a fork of the Citra 3DS Emulator on Android, and I’m currently stuck with this error: `C:/Users/X/AppData/Local/Android/Sdk/ndk/21.1.6352462/toolchains/llvm/prebuilt/windows-x86_64/lib/gcc/aarch64-linux-android/4.9.x/../../../../aarch64-linux-android/bin\ld: warning: libGLESv2.so, needed by ../../../../../../../externals/leia_sdk/lib/arm64-v8a/libleiasdk.so, not found (try using -rpath or -rpath-link)` My CMakeLists.txt looks like: ```auto add_library(lib_leia_sdk STATIC IMPORTED) set_target_properties(lib_leia_sdk PROPERTIES IMPORTED_LOCATION ${PROJECT_SOURCE_DIR}/externals/leia_sdk/lib/arm64-v8a/libleiasdk.so) target_include_directories(video_core PRIVATE ${PROJECT_SOURCE_DIR}/externals/leia_sdk/include) target_link_libraries(video_core PRIVATE EGL GLESv3 lib_leia_sdk) ``` The project itself uses GLAD, which I’m not familiar with, but, it seems to utilize EGL/GLES already? However, even if I explicitly include: ```auto #include #include ``` I still get the same error. I’ve detailed further information about the context of the issue here: > > > Hello again.

Revisited Your latest Beta and I am impressed! Do You think there is room for improvement or more specific for a few more frames per Second on certain Games? By the way Zelda Runs pretty good!
