无法在 CLion 中使用随 VCPKG 安装的库

Question

我按照 VCPKG github site 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我在 Clion 项目中更改的 CMakeLists.txt 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.

Answer 1

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

首先你需要安装你要使用的三元组，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。要使工具链成为默认设置，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

如果您选择了尚未安装 OpenMesh 三元组的工具链/架构，您将看到您遇到的确切错误。

vcpkg 为OpenMesh 8.1 提供了两个变量，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)
