I've downloaded LG's source and have tried to assimilate it into Slim's source (basically merging everything but the frameworks folder) and am now trying to build.
But this is the Ninja error I get:
ninja: Entering directory `.' ninja: error: '/home/android/Desktop/cheap_android_love/out/target/product/generic_arm64/obj/KERNEL_OBJ/usr', needed by '/home/android/Desktop/cheap_android_love/out/target/product/generic_arm64/obj/SHARED_LIBRARIES/libtinyalsa_intermediates/mixer.o', missing and no known rule to make it build/core/ninja.mk:151: recipe for target 'ninja_wrapper' failed make: *** [ninja_wrapper] Error 1
