Cannot find -lOpenCL on Android Studio (Compile Library)

[lucassardelari]

Hello friend, I'm trying to compile a project through Android Studio. But when I run the ndk build command, an exception occurs:

8 warnings generated. [arm64-v8a] SharedLibrary : libFerrugemLib.so C:/Android/Sdk/ndk-bundle/build//../toolchains/aarch64-linux-android-4.9/prebuilt/windows-x86_64/lib/gcc/aarch64-linux-android/4.9.x/../../../../aarch64-linux-android/bin\ld: cannot find -lOpenCL clang++.exe: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [obj/local/arm64-v8a/libFerrugemLib.so] Error 1 make: write error

Could you help me compile the command-lOpenCL

The error continues to occur, I will post a larger log to note:
