Multiple definitions

[gouarin]

I would like to use cxxopts in several source files but it seems that it is not possible. I have compilation errors mentioning that there exists multiple definitions.

To have an example, I just take the one given in the source code and I have added sum.hpp and sum.cpp with the following content

#ifndef SUM_HPP
#define SUM_HPP

#include "cxxopts.hpp"
double sum(double a, double b);
#endif  

#include "cxxopts.hpp"
#include "sum.hpp"

double sum(double a, double b)
{
    return a + b;
}

And then I have added

#include "sum.hpp"

and I have added the source file sum.cpp in the CMakeLists.txt. When you compile this example, you will have multiple definitions error.

I'll take a look at this.
