我在Win10 64位上安装了Visual Studio 2015社区。使用VS2015 x64 Native Tools Command Prompt shell，我找不到MASM可执行文件ml。我以为它是用VS安装的。我在运行nmake脚本作为Windows的OpenSSL构建过程的一部分时发现了这个问题。
ml /nologo /Cp /coff /c /Cx /Zi /Fotmp32dll\x86cpuid.obj tmp32dll\x86cpuid.asm
'ml' is not recognized as an internal or external command,
operable program or batch file.
NMAKE : fatal error U1077: 'ml' : return code '0x1'
Stop.
这是我的%PATH%：

MASM社区附带MASM，还是单独安装？这是我第一次使用MASM，因此我对Windows构建工具了解不少。
