Библиотека SDL не может быть найдена в cmake

Question

Я пытаюсь написать cmake. Я буду использовать OpenGL, SDL и OpenCV вместе. Дело в том, что операция cmake выполняется правильно, но если я ввожу команду make, она говорит, что «Нет такого файла или каталога» для SDL / SDL.h

мой cmake такой:

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}
    )

В исходном коде мои включения:

#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>

как последняя, ​​моя структура каталогов для проекта:

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

./src:
arucoDetect.cpp

и paths.cmake как руководство, я взял его у моего друга для того же проекта (но сложного):

# 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(OpenCV_DIR ${TOOLCHAIN_DIR}/opencv-odroid/share/OpenCV/)
ELSEIF(${ARCH} MATCHES "x86_64")

    set(OpenCV_DIR ${TOOLCHAIN_DIR}/opencv-host/share/OpenCV/)
ENDIF(${ARCH} MATCHES "aarch64")

# set Qt CMake paths

Я только начинаю использовать cmake, поэтому не могу найти что-то, что можно использовать правильно. Спасибо всем!

Answer 1

Благодаря @ Марко А. Я нашел проблему. Я использую SDL для кода, и я попытался включить SDL2. Я установил sdl1.2 и добавил привязку SDL. Чтобы установить SDL:

sudo apt-get install libsdl1.2-dev

и новый cmake:

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(SDL 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} 
    ${SDL_LIBRARY} 
    ${GLEW_LIBRARIES}
    ${OPENGL_LIBRARIES}
    )
