fatal error C1128 while compiling nnef.cpp in debug mode in VisualStudio 2015

[balaji-ch]

NNEF fails when compiled in debug mode but compiles in release mode.
\OpenVX-sample-impl\kernels\NNEF-Tools\parser\cpp\src\nnef.cpp : fatal error C1128: number of sections exceeded object file format limit: compile with /bigobj

Fix
Append /bigobj to ADD_C_FLAGS_DEBUG in OpenVX-sample-impl\cmake_utils\CMake_windows_tools.cmake
set (ADD_C_FLAGS_DEBUG "-D _DEBUG /RTC1 /MTd /bigobj") #/MTd /Gm
and build will work fine
