如何在支持libcrypto的Windows上构建PoDoFo?

我有一个使用PoDoFo支持PDF的项目,我正在尝试更新它,以使用SVN树中的HEAD版本。

与我使用的上一个版本相比,最大的变化是从OpenSSL添加了libcrypto,这似乎是必需的。我下载并构建了OpenSSL,并设置了适当的选项(或者我希望如此),以便cmake可以找到libcrypto。

cmake似乎觉得它还可以,但当我试图从生成的makefile进行构建时,我得到了错误:

Encrypt.cpp(50) : fatal error C1083: Cannot open include file: 'openssl/md5.h': No such file or directory

我精简了构建脚本,以便能够专注于这个问题:

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

我的 BuildSetup.cmake 文件:

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 "")

我尝试显式添加的路径 openssl/md5.h 到 INCLUDE 没有影响的环境变量。

我还尝试过使用“Visual Studio 10”生成器。同样的问题。
