Description

Page:
http://code.opencv.org/projects/opencv/wiki/Building_OpenCV4Android_from_trunk

OpenCV build -> Windows (native) section, the example command is 'cmake -DCMAKE_TOOLCHAIN_FILE=..\android\android.toolchain.cmake ..\..'

However if there is Visual Studio installed, this command will tell cmake to generate Visual Studio sln file instead of Makefile.
And during configuration time it will show errors on almost all Test HAVE_C???? tests. E.g. 'Performing Test HAVE_CXX_FSIGNED_CHAR - Failed'

To solve this problem, I found can simply add '-G "Unix Makefiles"' flag to cmake.

So it becomes:
cmake -G "Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=..\android\android.toolchain.cmake ..\..

And it will successfully generate Makefile, and then make is successful.
