title: full rebuild every time when building by CMake on Linux from Windows shared folder
body: <p>I'm using a script to build Windows and Linux versions (from Windows). Linux build is done by <code>ssh</code>ing to Linux VM and running CMake build. Sources are located on Windows folder shared with Ubuntu VM.</p>
  
  <p>CMake does full rebuild everytime, even if there's no changes since the last build. I suppose the problem is that CMake (or GCC?) doesn't get or reads incorrectly Windows NTFS timestamps.</p>
  
  <p>Is there any cure for this?</p>
  
  <p>CMake 3.7.1, GCC 4.9, Windows 10, Ubuntu 16.04 LTS, VirtualBox 5.1</p>
