when I start a emulator
emualtor -avd avd_name -gpu swiftshader_indirect
the program will add library search path "sdk/emulator/lib64/gles_swiftshader"
In order to realise the GPU software emulation, the program will use the /gles_swiftshade/*.so
SO, I have a doubt whether the /gles_swiftshade/*.so were generated by the source cod in AOSP/external/swiftshader ?
