Using prebuilt libraries on Android

When linking against FluidSynth on Android builds, you have to link not only fluidsynth.so but also all the other libraries that are included in the release, and some that are not included but are part of the Android NDK such as OpenMP. If you fail to do so your project may compile, but will fail at runtime because of missing dependencies.

CMake example

1. Add the fluidsynth library

	add_library(libfluidsynth SHARED IMPORTED)
	set(SHARED_LIBRARY_SO ${CMAKE_CURRENT_SOURCE_DIR}/../fluidsynth/lib/${CMAKE_ANDROID_ARCH_ABI}/libfluidsynth.so)
	set_target_properties(libfluidsynth PROPERTIES IMPORTED_LOCATION ${SHARED_LIBRARY_SO})

2. Add the dependencies included in the release

	add_library(libfluidsynth-assetloader SHARED IMPORTED)
	set_target_properties(libfluidsynth-assetloader PROPERTIES IMPORTED_LOCATION ${CMAKE_CURRENT_SOURCE_DIR}/../fluidsynth/lib/${CMAKE_ANDROID_ARCH_ABI}/libfluidsynth-assetloader.so)

Repeat the process with all the dependencies included (libFLAC, liboboe, libopus...).

3. Add the dependencies included in Android NDK (OpenMP)

find_package(OpenMP REQUIRED)

4. Put the pieces together under a single library

	add_library(fluidsynth INTERFACE)
	target_link_libraries(fluidsynth INTERFACE
		libFLAC
		libfluidsynth-assetloader
		libgio-2.0
		libglib-2.0
		libgmodule-2.0
		libgobject-2.0
		libgthread-2.0
		libinstpatch-1.0
		liboboe
		libogg
		libopus
		libpcre
		libpcreposix
		libsndfile
		libvorbis
		libvorbisenc
		libvorbisfile
		libfluidsynth
		OpenMP::OpenMP_CXX
	)

5. And finally link the library to your project!
