Unresolved External Symbol - FMT

Question

This is a strange error, because it only happens with this function:

#define FMT_HEADER_ONLY
#include <fmt/os.h>
#include <fmt/format.h>
#include <fmt/core.h>

int main() {
    auto out = fmt::output_file("guide.txt");
    out.print("Don't {}", "Panic");

    return 0;
}

Error:

Other functions like this works:

int main() {
    fmt::print(stderr, "Don't {}!", "panic");
    fmt::print(fmt::emphasis::bold | fg(fmt::color::red), "Elapsed time: {0:.2f} seconds", 1.23);
    return 0;
}

The headers and lib are included, so I don't understand where the problem is.
