在 cmake 中找不到 SDL 库

我正在尝试编写一个cmake。我将同时使用 OpenGL、SDL 和 OpenCV。问题是 cmake 操作正确完成，但如果我输入 make 命令，它会说 SDL/SDL.h "没有这样的文件或目录">

我的cmake是这样的：

cmake_minimum_required (VERSION 3.2)
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_AUTOMOC ON)
project (VisionTest)
# compiler version checking does not work if CMAKE_CXX_COMPILER is not set
if (CMAKE_CXX_COMPILER)
execute_process(COMMAND ${CMAKE_CXX_COMPILER} -dumpversion
OUTPUT_VARIABLE GCC_VERSION)
message("GCC version: ${GCC_VERSION}")
if (GCC_VERSION VERSION_GREATER "5.0.0" OR GCC_VERSION VERSION_EQUAL "5.0.0")
message(STATUS "GCC version >= 5.0, use CXX11_ABI=1")
else()
add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0)
endif()
endif()
find_package(OpenCV)
find_package(SDL2 REQUIRED)
find_package(OpenGL REQUIRED)
find_package(GLEW REQUIRED)
include_directories(
${GLEW_INCLUDE_DIR}
${OPENGL_INCLUDE_DIR}
${SDL2_INCLUDE_DIRS}
)
add_executable(
VisionTest
src/arucoDetect.cpp
)
target_link_libraries(VisionTest ${OpenCV_LIBS}
${SDL2_LIBRARY} 
${GLEW_LIBRARIES}
${OPENGL_LIBRARIES}
)

在源代码中，我包括：

#include "opencv2/highgui/highgui.hpp"
#include "opencv2/calib3d/calib3d.hpp"
#include "opencv2/core.hpp"
#include "opencv2/shape.hpp"
#include <opencv2/aruco.hpp>
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include <stdlib.h>
#include <stdio.h>
#include <sstream>
#include <vector>
#include <cmath>
#include <list>
#include <SDL/SDL.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/freeglut.h>
#include <GL/glut.h>
#include <algorithm>
#include <math.h>
#include <iostream>

最后，我的项目目录结构是：

CMakeCache.txt  Makefile   camera_calibration.cpp  paths.cmake
CMakeLists.txt  README.md  cmake_install.cmake     src
./src:
arucoDetect.cpp

和 paths.cmake 作为指导，我从我的朋友那里拿来了同一个项目(但很复杂(：

# define platform specific paths in this file
SET(TOOLCHAIN_DIR "/opt" CACHE STRING "")
include(cmake/TargetArch.cmake)
target_architecture(ARCH)
MESSAGE("TOOLCHAIN_DIR is set to:  ${TOOLCHAIN_DIR}")
MESSAGE("BUILDING FOR:  ${ARCH}")
#include target specific linker and include_directories
IF(${ARCH} MATCHES "aarch64")
set(QT5_DIR ${TOOLCHAIN_DIR}/qt5-odroid)
set(ZEROMQ_INCLUDE_PATH ${TOOLCHAIN_DIR}/zeromq-odroid/include)
set(ZEROMQ_LIB_PATH ${TOOLCHAIN_DIR}/zeromq-odroid/lib)
set(PROTOBUF_INCLUDE_PATH ${TOOLCHAIN_DIR}/protobuf-odroid/include)
set(PROTOBUF_LIB_PATH ${TOOLCHAIN_DIR}/protobuf-odroid/lib)

ENDIF(${ARCH} MATCHES "aarch64")

set(Qt5Qml_DIR ${QT5_DIR}/lib/cmake/Qt5Qml)
set(Qt5Network_DIR ${QT5_DIR}/lib/cmake/Qt5Network)

我刚刚开始使用 cmake，所以我找不到任何可以正确使用的东西。谢谢大家！
