无法在CLion中使用与VCPKG一起安装的库

Question

我按照VCPKG github site中描述的教程进行操作，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，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)

在Clion输出中返回以下错误：

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

下面的代码基于Visual Studio编译器，但应该可以很容易地应用到不同的环境中。

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，只需同时安装这两个三元组。)

在"Build，Execution，Deployment“下的"Toolchains”条目中选择适当的工具链。要使工具链成为默认，请使用小的向上和向下箭头将其移动到列表中的第一个条目。

​

​

在"Build，Execution，Deployment“下的"CMake”条目中选择工具链。

​

如果您选择了一个尚未安装OpenMesh三元组的工具链/体系结构，您将确切地看到您所遇到的错误。

vcpkg为OpenMesh 8.1提供了两个变量，需要使用这两个变量指定包含的目录和要链接的库，如下所示：

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

现在，此项目的整个CMakeLists.txt将如下所示：

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)
