# Prerequisites for Windows:
#     This cmake build is for Windows 64-bit only.
#
# Prerequisites:
#     You must have at least Visual Studio 2015 Update 3. 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.
#     You must have git.exe in your %PATH% environment variable.
#
# To build Rocksdb for Windows is as easy as 1-2-3-4-5:
#
# 1. Update paths to third-party libraries in thirdparty.inc file
# 2. Create a new directory for build artifacts
#        mkdir build
#        cd build
# 3. Run cmake to generate project files for Windows, add more options to enable required third-party libraries.
#    See thirdparty.inc for more information.
#        sample command: cmake -G "Visual Studio 15 Win64" -DWITH_GFLAGS=1 -DWITH_SNAPPY=1 -DWITH_JEMALLOC=1 -DWITH_JNI=1 ..
# 4. Then build the project in debug mode (you may want to add /m[:<N>] flag to run msbuild in <N> parallel threads
#                                          or simply /m to use all avail cores)
#        msbuild rocksdb.sln
#
#        rocksdb.sln build features exclusions of test only code in Release. If you build ALL_BUILD then everything
#        will be attempted but test only code does not build in Release mode.
#
# 5. And release mode (/m[:<N>] is also supported)
#        msbuild rocksdb.sln /p:Configuration=Release
#
# Linux:
#
# 1. Install a recent toolchain such as devtoolset-3 if you're on a older distro. C++11 required.
# 2. mkdir build; cd build
# 3. cmake ..
# 4. make -j
