我已经通过apt get安装了libsdl2映像开发程序，但cmake找不到它

我刚刚通过apt get安装了libsdl2 image dev，下面是我的“dpkg-L libsdl2 image dev”命令的结果：

但是，cmake中的“find_包（需要SDL2_映像）”抱怨：

CMake Error at CMakeLists.txt:34 (find_package):
  By not providing "FindSDL2_IMAGE.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "SDL2_IMAGE", but CMake did not find one.

  Could not find a package configuration file provided by "SDL2_IMAGE" with
  any of the following names:

    SDL2_IMAGEConfig.cmake
    sdl2_image-config.cmake

  Add the installation prefix of "SDL2_IMAGE" to CMAKE_PREFIX_PATH or set
  "SDL2_IMAGE_DIR" to a directory containing one of the above files.  If
  "SDL2_IMAGE" provides a separate development package or SDK, be sure it has
  been installed.


-- Configuring incomplete, errors occurred!

有人知道怎么修吗？谢谢

适用于x64 LINUX的

安装sdl2映像库

apt安装libsdl2映像开发人员

在cmake configs文件夹

/usr/lib/x86_64-linux-gnu/cmake/sdl2_image/sdl2_image-config.cmake中创建一个文件

把这个放进去

set(prefix "/usr") 
set(exec_prefix "${prefix}")
set(libdir "${prefix}/lib/x86_64-linux-gnu")
set(SDL2_IMAGE_PREFIX "/usr")
set(SDL2_IMAGE_EXEC_PREFIX "/usr")
set(SDL2_IMAGE_INCLUDE_DIRS "${prefix}/include/SDL2_image")
set(SDL2_IMAGE_LIBRARIES "-lSDL2_image")

然后添加到
CMakeLists.txt
以下内容

find_package(SDL2_image REQUIRED)
target_link_libraries(app SDL2_image)

错误消息中没有列出任何文件（
FindSDL2_IMAGE.cmake
、
SDL2_IMAGEConfig.cmake
或
SDL2_IMAGE-config.cmake
）。如果您遵循，那么它将说明文件
FindSDL2\u IMAGE.cmake
，您必须创建该文件，并通过
cmake\u模块路径
variable.Solved使其可搜索。谢谢
find_package(SDL2_image REQUIRED)
target_link_libraries(app SDL2_image)
