昨晚，在编译rabbitmq-c时，使用cmake生成vs项目文件时遇到下列错误：
CMake Error at C:/Program Files/CMake/share/cmake-3.6/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
system variable OPENSSL_ROOT_DIR (missing: OPENSSL_LIBRARIES
OPENSSL_INCLUDE_DIR) (Required is at least version "0.9.8")
Call Stack (most recent call first):
C:/Program Files/CMake/share/cmake-3.6/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
C:/Program Files/CMake/share/cmake-3.6/Modules/FindOpenSSL.cmake:380 (find_package_handle_standard_args)
CMakeLists.txt:273 (find_package)
经查，需要源码安装openssl以及需要相关头文件（为了简单起见，用过直接下载二进制版，不行）。故下载openssl 0.9.8g进行编译。
首先确保安装ActivePerl。
1、perl Configure VC-WIN32 no-asm
必须指定no-asm，不然后边很多编译会报错，指定--prefix=E:openssl可以安装到相应的目录。
2、msdo_nasm.bat
ms子目录下生成nt.make和ntdll.make文件，由于指定了no-asm，所以在这里必须是do_nasm而不是do_ms。
3、nmake -f ms tdll.mak
4、nmake -f ms tdll.mak install #安装到prefix指定的目录

相关错误：
第三步如果报：
.cryptocversion.c(105) : error C2220: 警告被视为错误 - 没有生成“object”文件
.cryptocversion.c(105) : warning C4129: “o”: 不可识别的字符转义序列
NMAKE : fatal error U1077: “"C:Program Files (x86)Microsoft Visual Studio 11.0VCBINcl.EXE"”: 返回代码“0x2”
Stop.
则打开ms tdll.mak文件，将其中的/WX去掉，如下：
如果报：
f:Microsoft Visual Studio 10.0VCINCLUDEerrno.h(92) : error C2220: warning treated as error - no 'object' file generated
f:Microsoft Visual Studio 10.0VCINCLUDEerrno.h(92) : warning C4005: 'EADDRINUSE' : macro redefinition
tmp32dlle_os.h(153) : see previous definition of 'EADDRINUSE'
NMAKE : fatal error U1077: '"f:Microsoft Visual Studio 10.0VCBINcl.EXE"' : return code '0x2' Stop.
则：.打开errno.h文件，找到第92行，注释掉#define EADDRINUSE 100
如果报'nmake' 不是内部或外部命令，也不是可运行的程序或批处理文件，则使用VS自带的cmd，如下：
