- Using OpenMP with C++11 range-based for loops?
#pragma omp parallel
{
#pragma omp single
{
for (auto x : stl_container)
{
#pragma omp task
{
// Do something with x, e.g.
compute(x);
}
}

#include <iostream>

int main(){
double sum_i = 0, max_i = -1;
#pragma omp parallel for reduction(+:sum_i) reduction(max:max_i)
for (int i=0; i<5000; i++){
sum_i += i;
if (i > max_i)
max_i = i;
}
std::cout << "Sum = " << sum_i << std::endl;
std::cout << "Max = " << max_i << std::endl;
return 0;

Is this explicit linking against OpenMP::OpenMP_CXX still necessary with this CMake linking command?
