title: How do you build PoDoFo on Windows with libcrypto support?
body: <p>I have a project which uses PoDoFo for PDF support and I am trying to update it to use the HEAD version from the SVN tree.</p>
  
  <p>The big change from the last version I used is the addition on libcrypto from OpenSSL, which seems to be required. I downloaded and built OpenSSL and set up the appropriate options (or so I had hoped) so that cmake could find libcrypto.</p>
  
  <p>cmake seems to find it ok, but when I try to build from the resulting makefile, I get the error:</p>
  
  <pre>
  Encrypt.cpp(50) : fatal error C1083: Cannot open include file: 'openssl/md5.h': No such file or directory
  </pre>
  
  <p>I whittled down my build script so that I could focus on this problem:</p>
  
  <pre>
  setlocal
  set ROOT=%CD%
  pushd podofo
  
  set CMAKE_PARAMS=-Wno-dev -C ..\BuildSetup.cmake . -DCMAKE_INSTALL_PREFIX:PATH=%1
  set CMAKE_PARAMS_RELEASE=-DCMAKE_BUILD_TYPE=Release %CMAKE_PARAMS%
  
  call "%VS100COMNTOOLS%..\..\vc\vcvarsall.bat" x86
  del CMakeCache.txt >nul
  rd /s /q CMakeFiles >nul
  
  set CMAKE_PREFIX_PATH=%ROOT%\install\zlib\x86
  set CMAKE_PREFIX_PATH=%CMAKE_PREFIX_PATH%;%ROOT%\install\freetype\x86
  set CMAKE_PREFIX_PATH=%CMAKE_PREFIX_PATH%;%ROOT%\install\libjpeg\x86
  set CMAKE_PREFIX_PATH=%CMAKE_PREFIX_PATH%;%ROOT%\install\libpng\x86
  set CMAKE_PREFIX_PATH=%CMAKE_PREFIX_PATH%;%ROOT%\install\openssl\x86
  set CRYPTO=-DLIBCRYPTO_INCLUDE_DIR=%ROOT%\install\openssl\x86\include
  set CRYPTO=%CRYPTO% -DLIBCRYPTO_LIBRARY_NAMES=libeay32
  
  cmake %CRYPTO% %CMAKE_PARAMS_RELEASE%\x86 -G "NMake Makefiles"
  cmake --build . --target install --clean-first
  
  popd
  endlocal
  </pre>
  
  <p>My <code>BuildSetup.cmake</code> file:</p>
  
  <pre>
  set (CMAKE_CONFIGURATION_TYPES "Debug;Release" CACHE STRING "config types" FORCE)
  set (CMAKE_INSTALL_PREFIX "../install" CACHE PATH "install path" FORCE)
  
  set (CMAKE_C_FLAGS_RELEASE "/MT /O1 /Ob2 /D NDEBUG" CACHE STRING "C release flags" FORCE)
  set (CMAKE_CXX_FLAGS_RELEASE "/MT /O1 /Ob2 /D NDEBUG" CACHE STRING "C++ release flags" FORCE)
  
  set (CMAKE_C_FLAGS_DEBUG "/D_DEBUG /MTd /Zi /Ob0 /Od /RTC1" CACHE STRING "C debug flags" FORCE)
  set (CMAKE_CXX_FLAGS_DEBUG "/D_DEBUG /MTd /Zi /Ob0 /Od /RTC1" CACHE STRING "C++ debug flags" FORCE)
  
  set (BUILD_SHARED_LIBS OFF CACHE STRING "")
  </pre>
  
  <p>I tried explicitly adding the path of <code>openssl/md5.h</code> to the <code>INCLUDE</code> environment variable with no effect.</p>
  
  <p>I also tried using the "Visual Studio 10" generator. Same problem.</p>
