无法在 CMAKE 项目中使用 XercesC
Failing to use XercesC in a CMAKE project
我正在尝试创建一个链接到 Windows 上的 xerces-c 的 CMAKE 项目。 Xerces-C 使用 cmake 构建并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
是我master里定义的变量CMakeLists.txt
set (XERCES_ROOT "" CACHE FILEPATH "Root directory of the Xerces-C installation")
我使用以下命令执行 cmake:
cmake -DBOOST_ROOT=D:\lib\Boost.69.0\ -DXERCES_ROOT=d:\lib\xercesc.2.2\ -G "Visual Studio 15 2017 Win64" ../
当我执行cmake时,我打印CMAKE_INCLUDE_PATH
的内容:
-- CMAKE_INCLUDE_PATH is D:/lib/xercesc/3.2.2
这是正确的位置。我在 find_package(XercesC REQUIRED)
行之前设置了这个变量。
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):

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?也许 CMAKE_INCLUDE_PATH
用法有误?
对于在您的项目中使用的关于外部包根目录的提示 CMake,可以在 CMAKE_PREFIX_PATH
变量中提示根目录:
cmake -DCMAKE_PREFIX_PATH=d:\lib\xercesc.2.2\ <other-options>
这样,您的 CMakeLists.txt
根本不需要理会这些提示:它只使用 find_package()
并期望一切正常。
另请参阅 ,了解使用 CMAKE_PREFIX_PATH
变量的其他方式以及该变量的其他功能。
