下面是我的CMakeLists文件：

set(LibName "VibraniumEngine")
set(RAYLIB_VERSION 4.2.0)
list(APPEND CMAKE_PREFIX_PATH "/dep/raylib/lib")
find_package(raylib)

if(NOT raylib)
    message(FATAL_ERROR "RayLib library not found")
else()
    message( "RayLib library found!")
endif()

这是我下载并尝试添加为依赖项的预构建raylib库的文件/文件夹结构：

正如您所看到的，我正在执行list(APPEND CMAKE_PREFIX_PATH "/dep/raylib/lib")，给出可以找到raylib的确切目录。
但是，我仍然收到此错误：

CMake Warning at Source/VibraniumEngine/CMakeLists.txt:4 (find_package):
  By not providing "Findraylib.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "raylib", but
  CMake did not find one.

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

    raylibConfig.cmake
    raylib-config.cmake

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

CMake Error at Source/VibraniumEngine/CMakeLists.txt:7 (message):
  RayLib library not found

你知道为什么吗？我该怎么修？
