in CMakeLists.txt you include filesystem twice (for UNIX and for ANDROID).

Around 970-980 line there is no guard for android. Should be,probably, like this:

---

elseif(UNIX AND NOT APPLE)

...

Around 970-980 line :

if(SDL_FILESYSTEM)
if(NOT ANDROID)
set(SDL_FILESYSTEM_UNIX 1)
file(GLOB FILESYSTEM_SOURCES ${SDL2_SOURCE_DIR}/src/filesystem/unix/*.c)
set(SOURCE_FILES ${SOURCE_FILES} ${FILESYSTEM_SOURCES})
set(HAVE_SDL_FILESYSTEM TRUE)
endif()
endif()

...

Also, you don't link with GLES. I'm not sure about this, but for me this solve the link problem. I manually added (around line 770):

if(ANDROID)

...

list(APPEND EXTRA_LDFLAGS "-Wl,--undefined=Java_org_libsdl_app_SDLActivity_nativeInit")

FIXME: Added manually

list(APPEND EXTRA_LDFLAGS "-ldl", "-lGLESv1_CM", "-lGLESv2", "-llog", "-landroid")
endif()

N.B. I see that you rise SDL_VIDEO_OPENGL_ES2 flag, but it seems that you not use it for now.

When building from Android Studio (which use clang, by default) it is also necessary to add following cflags:
"-Wa,-mimplicit-it=thumb", "-DGL_GLEXT_PROTOTYPES", "-DHAVE_PTHREADS"
