我按照VCPKG github站点中描述的教程 ,然后安装了OpenMesh 8.0,之后,我链接了工具链

-DCMAKE_TOOLCHAIN_FILE=/home/diolante/vcpkg/scripts/buildsystems/vcpkg.cmake 

在 Clion 工具链设置中以及当我重新加载CMakeLists.txt我在 Clion 项目中更改的内容时:

# CMakeLists.txt
cmake_minimum_required(VERSION 3.14)
project(lul)

find_package(openmesh REQUIRED)

add_executable(main main.cpp)
target_link_libraries(main openmesh)

Clion 输出返回以下错误:

CMake Error at /home/diolante/vcpkg/scripts/buildsystems/vcpkg.cmake:288 (_find_package):   By not providing "Findopenmesh.cmake" in CMAKE_MODULE_PATH this project has   asked CMake to find a package configuration file provided by "openmesh",   but CMake did not find one.

  Could not find a package configuration file provided by "openmesh" with any
  of the following names:

    openmeshConfig.cmake
    openmesh-config.cmake

  Add the installation prefix of "openmesh" to CMAKE_PREFIX_PATH or set
  "openmesh_DIR" to a directory containing one of the above files. If
  "openmesh" provides a separate development package or SDK, be sure it has
  been installed.

以下内容基于 Visual Studio 编译器,但应该很容易适用于不同的环境。

首先,您需要安装要使用的三元组,例如

vcpkg install openmesh --triplet x64-windows --triplet x86-windows

(如果您不确定是构建您的项目 x64 还是 x86,只需安装两个三元组。)

在“构建、执行、部署”下的“工具链”条目中选择正确的工具链。要使工具链默认设置,请使用向上和向下的小箭头将其移动到列表中的第一个条目。

在“构建、执行、部署”下的“CMake”条目中选择工具链

工具链选择2

如果您选择了尚未安装 OpenMesh 三元组的工具链/架构,您将准确看到您遇到的错误。

vcpkg为 8.1 提供了两个变量,OpenMesh它们需要用于指定包含目录和要链接的库,如下所示:

target_include_directories(main PRIVATE ${OPENMESH_INCLUDE_DIRS})
target_link_libraries(main PRIVATE ${OPENMESH_LIBRARIES})

这个项目的整个CMakeLists.txt现在看起来像这样:

cmake_minimum_required(VERSION 3.14)
project(lul)

find_package(openmesh REQUIRED)

add_executable(main main.cpp)
target_include_directories(main PRIVATE ${OPENMESH_INCLUDE_DIRS})
target_link_libraries(main PRIVATE ${OPENMESH_LIBRARIES})
# the following line is only needed for Visual Studio compilers
target_compile_definitions(main PRIVATE -D_USE_MATH_DEFINES)
