未能在CMAKE项目中使用XercesC

xerces-c xerces cmake c++

我正在尝试创建一个链接到Windows上xerces-c的CMAKE项目。Xerces-C是用cmake构建的,安装在一个文件夹中。这是安装的布局:

xercesc/3.2.2
  |
  |-bin
  |  |-xerces-c_3_2.dll
  |  |-xerces-c_3_2D.dll
  |  |-(many executables)
  |
  |-cmake
  |  |-XercesCConfig.cmake
  |  |-XercesCConfigInterna.cmale
  |  |-(other .cmake)
  |
  |-include
  |  |-xercesc
  |     |-dom
  |     |-framework
  |     |-internal
  |     |-parsers
  |     |-util
  |     |-(other folders)
  |
  |-lib
  |  |-xerces-c_3.lib
  |  |-xerces-c_3D.lib
  |
  |-share
     |-doc
        |-(documentation

这是我的CMakeFile.txt

cmake_minimum_required (VERSION 3.10.0)

project (myproject)

set (CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} ${XERCES_ROOT})
message (STATUS "CMAKE_INCLUDE_PATH is ${CMAKE_INCLUDE_PATH}")
find_package (XercesC REQUIRED)

set (CMAKE_INCLUDE_CURRENT_DIR ON)
include_directories (${CMAKE_CURRENT_SOURCE_DIR}/..)
include_directories (${XercesC_INCLUDE_DIR})

set (PROJECT_SRC
  Dummy.cpp
  )

add_library (${PROJECT_NAME} SHARED ${PROJECT_SRC})

XERCES_ROOT 是在我的master CMakeLists.txt中定义的变量

set (XERCES_ROOT "" CACHE FILEPATH "Root directory of the Xerces-C installation")

 cmake -DBOOST_ROOT=D:\lib\Boost\1.69.0\ -DXERCES_ROOT=d:\lib\xercesc\3.2.2\ -G "Visual Studio 15 2017 Win64" ../

当我执行cmake时,我打印 CMAKE_INCLUDE_PATH :

-- CMAKE_INCLUDE_PATH is D:/lib/xercesc/3.2.2

那是正确的位置。我将这个变量设置在 find_package(XercesC REQUIRED)

但是找不到包。这是错误消息:

CMake Error at C:/Program Files/CMake/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Failed to find XercesC (missing: XercesC_LIBRARY XercesC_INCLUDE_DIR
  XercesC_VERSION)
Call Stack (most recent call first):
  C:/Program Files/CMake/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
  C:/Program Files/CMake/share/cmake-3.13/Modules/FindXercesC.cmake:98 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  src/myproject/CMakeLists.txt:7 (find_package)


-- Configuring incomplete, errors occurred!

我做错了什么?我该怎么做才能告诉CMAKE在哪里可以找到Xerces?大概 CMAKE_INCLUDE_路径

对于在您的项目中使用的关于外部包根的提示CMake,可以提示root-in CMAKE_PREFIX_PATH 变量:

cmake -DCMAKE_PREFIX_PATH=d:\lib\xercesc\3.2.2\ <other-options>

这样,你的 CMakeLists.txt 根本不需要担心这些提示:它只是使用 find_package()

另见 that my answer 关于其他使用方法 CMAKE_前缀_路径 变量和该变量的其他特性。
