编译 MATIO 库时出错：“对‘Mat_Open’的未定义引用”

问题描述

所以在使用 CMake 构建和安装 MATIO 库之后，我现在在编译它时遇到了问题。这是我的代码：

#include <iostream>
#include <matio.h>
#define tS(x) std::cout<<"\t"<<(#x)<<" == "<<(x)<<"\n" 
int main(int argc,char **argv)
{
    const char *fileName = argc==1?"./S.mat":argv[1] ;
    mat_t *mat = Mat_Open(fileName,MAT_ACC_RDONLY);
    if(mat)
    {
        std::cout<<"A file was opened for reading\n\tmat == "<<mat<<"\n" ;

        matvar_t *matvar=0 ;
        std::cout<<"Writing out the data\n\n" ;
        std::cout<<"x:\n" ;
        matvar = Mat_VarRead(mat,(char*)"x") ;
        if(matvar)
        {
            int xSize = matvar->nbytes/matvar->data_size ;
            const double *xData = static_cast<const double*>(matvar->data) ;
            for(int i=0; i<xSize; ++i)
            {
                std::cout<<"\tx["<<i<<"] = "<<xData[i]<<"\n" ;
            }
            std::cout<<"\n" ;
            for(int i=0; i<matvar->rank; ++i)
            {
                std::cout<<"\tdim["<<i<<"] == "<<matvar->dims[i]<<"\n" ;
            }
        }

        std::cout<<"y:\n" ;
        matvar = Mat_VarRead(mat,(char*)"y") ;
        int ySize = matvar->nbytes/matvar->data_size ;
        const double *yData = static_cast<const double*>(matvar->data) ;
        for(int i=0; i<ySize; ++i)
        {
            double d = yData[i] ;
            std::cout<<"\ty["<<i<<"] = "<<d<<"\n" ;
        }
        std::cout<<"\n" ;
        for(int i=0; i<matvar->rank; ++i)
        {
            std::cout<<"\tdim["<<i<<"] == "<<matvar->dims[i]<<"\n" ;
        }

        Mat_Close(mat);
    }
    else
    {
        std::cout<<"File cannot be opened\n" ;
        return 1;
    }
    return 0;
}

但是我收到以下错误：

我左右查找了这个错误，我知道链接器由于某种原因找不到库，尽管我有以下编译器选项： -g;-O0;-Wall;-I/Users/RS3/matio/getopt;-I/matio/include;-L/matio/bin;-lmatio

我使用的是 Codelite IDE。

我不确定我错过了什么，这让我发疯。任何帮助将不胜感激！
