我正在尝试为使用 GLEW 的项目设置一个 CMakeLists.txt 文件。我一直这样做：
find_path(GLEW_INCLUDE_DIR GL/glew.h)
find_library(GLEW_LIBRARY_RELEASE glew32)
find_library(GLEW_LIBRARY_DEBUG glew32d)
target_include_directories(${APP_NAME} PUBLIC ${GLEW_INCLUDE_DIR})
target_link_libraries(${APP_NAME} optimized ${GLEW_LIBRARY_RELEASE}
debug ${GLEW_LIBRARY_DEBUG})
这种方法有效，但我想使用 find_package 方法，因为我认为它更好。
我在这个网站上找到了一些示例，例如：Adding GLEW to project (CMake)，建议执行如下操作：
find_package(GLEW REQUIRED)
target_link_libraries(${APP_NAME} GLEW::GLEW)
但是当我尝试这样做时，它在配置阶段会产生错误：
