+Build Instructions for MySQL Server
+===================================
+
+The recommended way to build MySQL for developers:
+
+cd <some build directory>
+cmake <path to source directory>
+make
+
+This will give you a release (actually RelWithDebInfo) build,
+with compiler options taken from
+../cmake/build_configurations/compiler_options.cmake
+
+Adding -DWITH_DEBUG=1 to the cmake command line gives you a debug build.
+
+
+Building on Windows is slightly different:
+cd <some build directory>
+cmake <path to source directory> -G <generator>
+
+We only support Visual Studio as generator and only 64 bit ("Win64").
+
+cmake --build . --config Debug
+or
+cmake --build . --config RelWithDebInfo
+
+You can pass options to msbuild, see
+https://docs.microsoft.com/en-us/visualstudio/msbuild/msbuild-command-line-reference?view=vs-2019
+
+To speed up compilation, building multiple projects in parallel:
+cmake --build . --config Debug -- -m
+
+To have a completely silent build:
+cmake --build . --config Debug -- -v:q
+
+Or combined:
+cmake --build . --config Debug -- -m -v:q
+
+
+If you have special needs, you can disable the defaults by setting
+this cmake variable off: WITH_DEFAULT_COMPILER_OPTIONS
+
+Building MySQL from source requires SSL headers and libraries to be
+available. The default value for the cmake variable WITH_SSL is "system".
+This means that on UNIX systems, you should install the appropriate
+OpenSSL developer package.
+
+For Windows users, please see
+   https://wiki.openssl.org/index.php/Binaries
+For Mac users, please see
+   http://brewformulas.org/Openssl
+
+You may also build OpenSSL yourself, and do
+   cmake -DWITH_SSL=</path/to/custom/openssl>
+in order to build MySQL.
+===
+
+It is possible to compile with Clang on Windows, which compiles faster
+and also yields faster binaries, but this is experimental and not officially
+supported. To compile, install the most recent version from
+https://github.com/llvm/llvm-project/releases
+(Clang/C2, which is Microsoft's own version of Clang, is not supported)
+
+Ensure that you have ninja and cmake in your path.
+Source the appropriate vcvarsall.bat file which comes with Visual Studio,
+so that Visual Studio executables are in your PATH.
+
+cmake -G Ninja -DFORCE_UNSUPPORTED_COMPILER=1
+  -DCMAKE_C_COMPILER="C:/Program Files/LLVM/bin/clang-cl.exe"
+  -DCMAKE_CXX_COMPILER="C:/Program Files/LLVM/bin/clang-cl.exe"
+  -DCMAKE_LINKER="C:/Program Files/LLVM/bin/lld-link.exe"
+  -DWITH_BOOST=<path to Boost> ..
+
+ninja
+
+This configuration also supports ASAN (-DWITH_ASAN=1), although currently only
+when linking with MSVC's linker (not with LLD).
+
+For running tests with --parallel, you may need to add --build-thread= (500 is
+a reasonable value to try).
+
+===
+
+Note: You need to tell cmake where to find boost, see ../cmake/boost.cmake
