C++ 如何向CMake提供vcpkg信息？

假设我安装了一些带有

vcpkg

的库，并且它有许多依赖项（比如

cgal

）。现在我想用

CMake

针对这些库编译一些程序

我应该如何告诉

CMake

我下载的所有库的所有位置？包括我安装的主库？在

CMake

中，我只有一个名为“源目录”的设置，它将指向我的代码。图书馆的设置在哪里

通常你需要设置<代码>CMAKE_工具链_文件和

VCPKG_目标_三元组

将

vcpgg\u TARGET\u三元组设置为您正在使用的vcpgg三元组。默认值为x86 windows

将

CMAKE\u工具链\u文件

设置为指向\u vcpkg\scripts\buildsystems\vcpkg.CMAKE的

path\u

然后，您可以使用cmake函数（如
find_package
）来查找所需的包

有关更多信息，请参阅。
设置CMAKE\u工具链\u文件”是什么意思？这是否意味着在外壳中使用set？这是否意味着在CMakeLists.txt中添加一行设置？这是否意味着使用-DCMAKE。。。在cmake命令行上？@sigfpe将其用作-DCMAKE_TOOLCHAIN_FILE=path_to_vcpkg\scripts\buildsystems\vcpkg.cmake我不确定是否有其他方法，但这一种有效，请确保首先执行“vcpkg集成安装”。

CMake Warning at CMakeLists.txt:18 (find_package):
  By not providing "FindCGAL.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "CGAL", but
  CMake did not find one.

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

    CGALConfig.cmake
    cgal-config.cmake

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