Error when compiling MATIO library: "Undefined reference to 'Mat_Open'" - c++

Question

so after building and installing the MATIO library using CMake, I am now having problems compiling it. Here's my code:
#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;
}
However I get the following error:

I looked for this error right and left and I know the linker can't find the library for some reason despite me having the following compiler options:
-g;-O0;-Wall;-I/Users/RS3/matio/getopt;-I/matio/include;-L/matio/bin;-lmatio
I'm using Codelite IDE.
I am not sure what I am missing and it's driving me crazy. Any help would be appreciated!
