Generate Self-Contained MSVC 2017 Toolchain

generate_msvc17_toolchain.bat

REM
REM Generate Standalone MSVC17 x86/x64 Toolchain from VS Installation
REM
REM Collects the necessary includes, binaries, DLLs and libs to around ~300mb on
REM disk from a VS installation that can invoke cl, and link as you typically
REM would after calling "vcvarsall.bat x64"
REM
REM This script generates the helper scripts within the generated toolchain.
REM cl_[x64|x86].bat:       Invokes the compiler with required environment variables set
REM link_[x64|x86}.bat:     Invokes the linker with required environment variables set
REM msvc_env_[x64|x86].bat: Setups the environment variables for the toolchain.
REM                         i.e. "call msvc_env_x64.bat" to set the current
REM                         session's environment variables for compiling with
REM                         the toolchain, akin to "vcvarsall.bat x64"
