如何添加OpenGL&GLUT for Windows上的CLion? [英] How add OpenGL & GLUT for CLion on Windows?

问题描述

我已经安装了OpenGL和Glut，但是当我尝试运行它时-出现此错误.我安装错了吗?还是应该编辑CMake文件?

I have installed OpenGL and Glut but when I'm trying to run it - get this error. Have I installed something wrong? Or should I edit CMake file?

project(LW1)

set(CMAKE_CXX_STANDARD 17)

include_directories(OpenGL)
include_directories(OpenGL/include) # OpenGL/include has to contain the required OpenGL's .h files
include_directories(OpenGL/lib) # OpenGL/lib has to contain the required OpenGL's .lib files



add_custom_target(glutdlllib
        COMMAND ${CMAKE_COMMAND} -E copy LW1/OpenGL/dll/glut32.dll ${CMAKE_BINARY_DIR}
        )

set(OpenGlLibs glaux glu32 glui32 glut32 opengl32 )


#These 3 lines are just linking and making executables

add_executable(LW1 main.cpp)

target_link_libraries(LW1 ${OpenGlLibs})

add_dependencies(LW1 glutdlllib)

target_link_libraries(LW1 -lOpenGL32 -lfreeGLUT)

main.cpp:

#include <windows.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glaux.h>
#include <glut.h>

void resize(int width, int height)
{
}
void display(void) {
    glColor3d(1,1,0);
    glutSolidSphere(1.0, 25, 25);
    glFlush();
}
void init(void) {
    glEnable(GL_COLOR_MATERIAL);
    glEnable(GL_LIGHTING);
    glEnable(GL_LIGHT0);
    glEnable(GL_DEPTH_TEST);
    glClearColor(0.0, 0.0, 0.0, 0.0);
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glMatrixMode(GL_PROJECTION);;
    glLoadIdentity();
    glOrtho(-5.0, 5.0, -5.0, 5.0, 2.0, 12.0);
    gluLookAt(0,0,5, 0,1,0, 0,1,0);
    glMatrixMode(GL_MODELVIEW);
}
int main(int argc, char ** argv) {
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB | GLUT_DEPTH);
    glutInitWindowPosition(50, 10);
    glutInitWindowSize(400, 400);
    glutCreateWindow("Hello");
    glutReshapeFunc(resize);
    init();
    glutDisplayFunc(display);
    glutMainLoop();
    return 0;
}

错误:

推荐答案

add_custom_target 中的命令是在将工作目录设置为构建目录的情况下执行的.因此，您给出的相对路径将被解释为相对于构建目录.

The command in add_custom_target is executed with the working directory set to your build directory. The relative path you give is thus interpreted as relative to the build directory.

将工作目录设置为 CMAKE_CURRENT_SOURCE_DIR 或使用它在复制命令中将相对路径转换为绝对路径.

Either set the working directory to CMAKE_CURRENT_SOURCE_DIR or use it convert the relative path to an absolute one in your copy command.
