Errors in building for android: not found and openBlas failed to compile

from caffe-mobile.

@Siddhant24 I guess it's the NDK version problem. NDK version r16 (and later) changed a lot of things. Adding some special arguments or changing it to r15 could solve the problem. I'll re-check this problem and find a way to fix it.

@solrex I also posted this issue on stackoverflow. Some suggestions in the comments.

Using NDK version r15 resolved openBLAS build problem. Now I get the following errors:

CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

CMakeOutput.log has the following contents:

@Siddhant24 Do you have "make" installed? Try "which make".

[Siddhant24]

@solrex Yes I have "make" installed.
"which make" returns usr/bin/make

@Siddhant24
after hours of checking here and there,
i finally found the solution to the problem,
downgrade/upgrade cmake to 3.7.2
