C++ Use of deleted function error

I'm getting a lot of use of deleted function error. I just changed the pointer of weighted_pointer to unique_ptr. But I can't realize why I'm getting the error, any tip?

The likeatree is a DAG structure which can point to another struct or an element of stdDeque based on mask value.

The weight of weighted_pointer has mutable keyword because doesn't change where in the set will be.

#include <deque>
#include <set>
#include <vector>
#include <iostream>
#include <algorithm>
#include <memory>
#include <chrono>

using namespace std;

struct likeatree{
    unsigned int mask : 3;
    void * a;
    void * b;
};

struct weighted_pointer{
    mutable int weight;
    unique_ptr<likeatree> ptr;
};

struct ptrcomp{
    bool operator()(const weighted_pointer lhs, const weighted_pointer rhs) {
        if(lhs.ptr->mask < rhs.ptr->mask)
            return true;
        if(lhs.ptr->mask > rhs.ptr->mask)
            return false;
        if(lhs.ptr -> a < rhs.ptr->a)
            return true;
        if(lhs.ptr->a > rhs.ptr->a)
            return false;
        return lhs.ptr->b < rhs.ptr->b;
    }
};

vector<likeatree *> treeVector;
deque<bool> stdDeque(3);
vector<vector<bool>> boolMatrix{{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0}};
set<weighted_pointer,ptrcomp> stdSet;

int main(){
    srand(time(NULL));
    weighted_pointer tmp;
    tmp.weight = 1;
    for(unsigned int i = 0; i < stdDeque.size(); i++){
        tmp.ptr.reset(new likeatree{0,&stdDeque[i],nullptr});
        stdSet.insert(tmp);
    }
    for(unsigned int i = 0; i < boolMatrix.size(); i++){
        treeVector.push_back(tmp.ptr.get());
    }
    for(unsigned int i = 0; i < treeVector.size(); i++){
        auto it = find_if(stdSet.begin(),stdSet.end(),[&](weighted_pointer temp){ return temp.ptr.get() == treeVector[i]; });
        /* ... */
    }
    return 0;   
}
