我正在尝试构建PoDoFo，但与 OpenSSL 相关的链接器错误很少（我认为）。我尝试构建它（OpenSSL），但它太复杂了，所以我从http://slproweb.com/products/Win32OpenSSL.html下载了 Win64 OpenSSL v1.0.1e 。
我用这段代码制作了 Visual Studio 解决方案：
del cmakecache.txt
set FTDIR=D:\Iwan\Projekty\PDF_projekt\freetype-2.4.11
set FTLIBDIR=D:\Iwan\Projekty\PDF_projekt\freetype-2.4.11\objs\win32\vc2010
set JPEGDIR=D:\Iwan\Projekty\PDF_projekt\jpeg-9
set ZLIBDIR=D:\Iwan\Projekty\PDF_projekt\zlib127-dll
set LIBCRYPTODIR=C:\OpenSSL-Win64
cmake -G "Visual Studio 10" ..\podofo-0.9.2 -DCMAKE_INCLUDE_PATH="%FTDIR%\include;%JPEGDIR%\include;%JPEGDIR%;%ZLIBDIR%\include;%LIBCRYPTODIR%\include;%LIBCRYPTODIR%\include\openssl" -DCMAKE_LIBRARY_PATH="%FTLIBDIR%;%FTDIR%\lib;%JPEGDIR%\lib;%JPEGDIR%;%ZLIBDIR%\lib;%LIBCRYPTODIR%\lib\VC" -DPODOFO_BUILD_SHARED:BOOL=TRUE -DFREETYPE_LIBRARY_NAMES_DEBUG=freetype2411MT_D -DFREETYPE_LIBRARY_NAMES_RELEASE=freetype2411MT -DLIBCRYPTO_LIBRARY_NAMES_DEBUG=libeay32MDd -DLIBCRYPTO_LIBRARY_NAMES_RELEASE=libeay32MD
我不确定我应该在选项中添加什么库，但我尝试了 libeay32MD、sleay32MD、libeay32MT、ssleay32MT、libeay32 和 ssleay32。
当我尝试编译创建的解决方案时，我得到了这些链接器错误：

我试图编译这个 2 天，但我没有做任何工作，我在互联网上找不到任何东西。
