CMake Error: The source directory ... does not appear to contain CMakeLists.txt

[acenter2507]

Here is what i am getting on building torch-android on Ubuntu. Any ideas?

Android NDK found at: ~/android-ndk-r14b/ INSTALL_DIR=~/torch-android/install CMake Error: The source directory "~/torch-android/external/libpng" does not appear to contain CMakeLists.txt. Specify --help for usage, or press the help button on the CMake GUI. -------------- Configuring DONE --------------- make: *** No rule to make target 'install'. Stop.

Many thanks!

I think broblem is below.

fatal: reference is not a tree: 2964a877aeeb02a66eeba084ceb1dfa3c6836f1b Unable to checkout '2964a877aeeb02a66eeba084ceb1dfa3c6836f1b' in submodule path 'external/libpng'

After i manually copy external/libpng from borisfom/platform_external_libpng, run build.sh and the compile also failed.
