Question

我认为，我可能不正确地将cmake设置为错误，（或为此不正确地设置了cmake），或者我对C ++或同时对这两者感到不满和生锈，甚至更多。我只想添加一个标头并将单独的代码添加到为opengl加载图像的类中。我还将它们放在与Linux文件树中其他库并行的另一个目录中。

主项目文件夹中包含main cmakelists.text文件，该文件称为“ maficengine”。内部还有一个“ build”文件，一个“ common”文件和“ external”文件以及一个名为“ Mafic”，“ maficGuiSourceFiles”的文件和一个名为“ distrib”的文件。我认为我们可以只专注于2.“ mafic”和“ external”。在mafic中，我有一个名为mafic.cpp的文件，它具有我的主要功能，并且是入口点。在外部文件中，还有一个名为“ myCustomHeaders”的文件夹。其中包含一个名为“ loadTexture.cpp”的文件，其中包含loadTexture类的声明和定义。同样在“ myCustomHeaders”内部，有一个“包含”文件，其中包含“ loadTexture.h”……我似乎无法实例化LoadTexture lt的实例；并调用loadtexture（）函数；我希望它在mafic.cpp中的第187行

target_link_libraries(mageengine

这是mafic.cpp


#include <loadTexture.h>


int main( void )
{

loadTexture lt;

 lt.loadtexture();
 }

这是我的loadTexture.cpp




class loadTexture
{

public:

loadTexture();

~loadTexture();

void loadtexture(){



fprintf(stdout, "loadtexture does something, that's a positive result for this test");



}




};

最后是我的loadTexture.h

[code] 
#pragma once

#include <GL/glew.h>

//GLuint image;
void loadtexture();
[/code]

希望它不会出错，但我得到...

我认为cmake没有链接我的课程，cmakelists.text中的错误可能是罪魁祸首
