將預處理器定義添加到cmake外部項目

我想在Windows上使用cmake ExternalProject將xerces-c構建爲靜態庫。然而，爲了這個工作，我需要將XERCES_STATIC_LIBRARY預處理器定義添加到項目中。在Linux上，似乎我可以用補丁文件輕鬆完成，但我不確定如何在Windows上執行此操作。將預處理器定義添加到cmake外部項目

這裏是我當前的CMakeLists.txt：

cmake_minimum_required(VERSION 3.0.0 FATAL_ERROR) 
PROJECT(xercesc) 
SET(TARGET_NAME xercesc) 

IF(WIN32) 
    # find the msvc version 
    if(${MSVC_VERSION} EQUAL 1400) 
     SET(VC_PROJ_DIR VC8) 
    elseif(${MSVC_VERSION} EQUAL 1500) 
     SET(VC_PROJ_DIR VC9) 
    elseif(${MSVC_VERSION} EQUAL 1600) 
     SET(VC_PROJ_DIR VC10) 
    elseif(${MSVC_VERSION} EQUAL 1700) 
     SET(VC_PROJ_DIR VC11) 
    elseif(${MSVC_VERSION} EQUAL 1800) 
     SET(VC_PROJ_DIR VC12) 
    endif(${MSVC_VERSION} EQUAL 1400) 

    include(ExternalProject) 
    ExternalProject_Add(
     ${TARGET_NAME} 
     URL ${CMAKE_CURRENT_SOURCE_DIR}/xerces-c-${XERCESC_VERSION}.tar.gz 
     DOWNLOAD_DIR ${CMAKE_CURRENT_SOURCE_DIR}/xercesc 
     SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/xercesc 
     CONFIGURE_COMMAND "" 
     BUILD_COMMAND Devenv "${CMAKE_CURRENT_SOURCE_DIR}/xercesc/projects/Win32/${VC_PROJ_DIR}/xerces-all/xerces-all.sln" /build Release 
     INSTALL_COMMAND "" 
     BUILD_IN_SOURCE 1 
    ) 
ENDIF(WIN32)

'ExternalProject_Add'不提供命令行上面的功能。由於你有VS解決方案，它已經*配置*，所以編譯器定義只能通過補丁來添加。 – Tsyvarev

從Devenv切換到msbuild命令行的祕密醬。它功能更強大，您可以使用/property:DefineConstants=XERCES_STATIC_LIBRARY定義常量。注意：它會吹掉項目文件中定義的其他常量...但是你不會愚蠢到在cmake構建中的.vcxproj文件中定義常量，你會嗎？

因此無論如何，下面是在Windows上構建xerces-c的完整解決方案。請注意，對於靜態構建，他們使用配置名稱中的（上帝被遺棄的）空格。最簡單的解決方法是用下劃線替換它們並隨着生活繼續前進。我用the find and replace text (FART) tool。

此外，我正在做一個DLL運行時庫構建，所以我替換了所有的/ MT選項。
