cmake cannot find OpenAL (missing OPENAL_LIBRARY OPENAL_INCLUDE_DIR ?)

[stav]

HI
I'm trying to build sfml for android.

I invoke cmake with the following command:

Code: [Select]

cmake -DCMAKE_SYSTEM_NAME=Android -DCMAKE_TOOLCHAIN_FILE=/home/stav/Android/Sdk/ndk-bundle/build/cmake/android.toolchain.cmake -DCMAKE_ANDROID_NDK=/home/stav/Android/Sdk/ndk-bundle/ -DCMAKE_ANDROID_ARCH_ABI=x86 -DCMAKE_ANDROID_STL_TYPE=c++_static -DCMAKE_BUILD_TYPE=Debug ../..

but im getting this error:

Code: [Select]

CMake Error at /usr/share/cmake-3.12/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

even though i have installed all the dependencies (including OpenAL)
can someone help me?
