# This cmake build is for Windows only.
#
# Prerequisites:
#     You must have Visual Studio 2013 Update 4 installed. Start the Developer Command Prompt window that is a part of Visual Studio installation.
#     Run the build commands from within the Developer Command Prompt window to have paths to the compiler and runtime libraries set.
#     Make sure that Git is in your PATH
#
# To build Rocksdb for Windows is as easy as 1-2-3-4-5:
# 
# 1. Update paths to thirdparty libraries in thirdparty.cmake file
# 2. Create a new directory for build artifacts
#        mkdir build
#        cd build
# 3. Run cmake to generate project files for Windows
#        cmake -G "Visual Studio 12 Win64" ..
# 4. Then build the project in debug mode (you may want to add /m:<N> flag to run msbuild in <N> parallel threads)
#        msbuild ALL_BUILD.vcxproj
# 5. And release mode (/m:<N> is also supported)
#        msbuild ALL_BUILD.vcxproj /p:Configuration=Release
#
