vs 编译 openssl

• Extract the source code to a new clean folder - failed appempts seem to leave a lot of crap

• Download Nasm.exe if you don't already have it - http://www.nasm.us/. Just put it in C:WindowsSystem32 (or in your path)

• Start the VS2017 X86 Command prompt - and run the following:

  "c:Program Files (x86)Microsoft Visual Studio 12.0VCvcvarsall.bat"
  perl Configure VC-WIN32 --prefix=C:Build-OpenSSL-VC-32
  msdo_nasm.bat
  nmake -f ms t.mak
  nmake -f ms t.mak install

要注意的一点就是编译x86的需要下载安装Nasm
