如何使用cmake和vcpkg在MacOS上导入GLAD/GLFW3/ImGUI库?

Question

我的目标是使用ImGUI编写一个简单的、可移植的应用程序。我还希望使用cmake和vcpkg安装依赖项的平台无关构建体验。我在我的Windows电脑上构建并运行了该程序，但在我的Macbook (macOS Monterey 12.6)上却无法运行。

这是我的vcpkg.json:

{
"name": "imguitest",
"version": "1.0",
"dependencies": [
"glad",
"glfw3",
{
"name": "imgui",
"features": [ "glfw-binding", "opengl3-binding" ]
}
]
}

这是我的CMakeLists.txt:

cmake_minimum_required (VERSION 3.23)
project(ImGui-Test)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${PROJECT_SOURCE_DIR}/bin)
add_executable(${PROJECT_NAME}
src/main.cpp
)
find_package(glad CONFIG REQUIRED)
target_link_libraries(${PROJECT_NAME} PRIVATE glad::glad)
find_package(glfw3 CONFIG REQUIRED)
target_link_libraries(${PROJECT_NAME} PRIVATE glfw)
find_package(imgui CONFIG REQUIRED)
target_link_libraries(${PROJECT_NAME} PRIVATE imgui::imgui)
find_package(OpenGL REQUIRED)
target_link_libraries(${PROJECT_NAME} PRIVATE OpenGL::GL)

运行后:

# export VCPKG_DIR=/path/to/vcpkg/repo/
cmake -B ./build -S . "-DCMAKE_TOOLCHAIN_FILE=$VCPKG_DIR/scripts/buildsystems/vcpkg.cmake"

我得到这个错误:

CMake Error at CMakeLists.txt:14 (find_package):
Could not find a package configuration file provided by "glad" with any of
the following names:
gladConfig.cmake
glad-config.cmake
Add the installation prefix of "glad" to CMAKE_PREFIX_PATH or set
"glad_DIR" to a directory containing one of the above files.  If "glad"
provides a separate development package or SDK, be sure it has been
installed.

我必须自己手动安装GLAD包并设置路径吗?我认为vcpkg会为我处理这个问题。如果我误解了什么，请告诉我，因为我是现代cmake和vcpkg的新手。

这个修复了:brew install pkg-config

我得到了更多的描述性错误信息后，我删除了build文件夹。当使用vscode配置cmake时，这个错误信息是隐藏的，但是当通过zsh终端配置时，这个错误信息是可见的。
