我想在Windows的CMake项目中使用vcpkg
,因为我需要boost
和xerces
,这两个都是由这个软件包管理器处理的。
我有以下的CMakeLists.txt
:
cmake_minimum_required (VERSION 3.12.0)
project (myproj)
set (CMAKE_PREFIX_PATH ${XERCES_ROOT})
set (Boost_USE_STATIC_LIBS ON)
set (Boost_USE_MULTITHREADED ON)
unset (Boost_INCLUDE_DIR CACHE)
unset (Boost_LIBRARY_DIRS CACHE)
# set (CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/../../cmake/modules)
find_package (Boost COMPONENTS filesystem regex REQUIRED)
find_package (XercesC CONFIG REQUIRED)
set (CMAKE_INCLUDE_CURRENT_DIR ON)
message (STATUS "binary dir is ${CMAKE_BINARY_DIR}")
include_directories (${CMAKE_BINARY_DIR}/${PROJECT_NAME}/)
include_directories (${CMAKE_CURRENT_SOURCE_DIR}/..)
include_directories (${Boost_INCLUDE_DIRS})
include_directories (${XercesC_INCLUDE_DIRS})
set (PROJECT_SRC
code.cpp
)
add_library (${PROJECT_NAME} SHARED ${PROJECT_SRC})
add_dependencies (${PROJECT_NAME} UPDATE_RESOURCES)
target_link_libraries (${PROJECT_NAME} ${Boost_LIBRARIES} XercesC::XercesC)
Boost
和xerces-c
已经通过vcpkg
安装。由于我使用的是Visual Studio Code,因此我在settings.json
中设置了vcpkg
变量:
"cmake.configureSettings": {
"CMAKE_TOOLCHAIN_FILE" : "some/path/vcpkg/scripts/buildsystems/vcpkg.cmake",
"VCPKG_TARGET_TRIPLET": "x64-windows"
}
当我运行CMake时,我会得到以下错误:
[cmake] CMake Error at C:/Program Files/CMake/share/cmake-3.14/Modules/FindBoost.cmake:2132 (message):
[cmake] Unable to find the requested Boost libraries.

目前我已经使用vcpkg命令安装了xerces
,但是boost目前没有安装,但我期望在执行cmake命令的时候,vcpkg
会下载并构建所需的构建包。
我也尝试过命令行:
cmake -DCMAKE_TOOLCHAIN_FILE=D:/Projects/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows ../
但结果却相同。
我做错了什么?如何才能成功使用vcpkg?
