[SOLVED] Undefined references when linking Google Benchmark with g++ on Windows (MSYS2) using vcpkg

I'm trying to use Google Benchmark with the g++ compiler on Windows. I installed the library using the vcpkg package manager with the triplet x64-mingw-static.

Here is the command I used to install it:

vcpkg install benchmark:x64-mingw-static

I have verified that the files benchmark.a and benchmark_main.a exist in the specified directory. Here is the command:

g++ -std=c++23 test_benchmark.cpp -isystem "C:\\Program Files\\vcpkg\\installed\\x64-mingw-static\\include" -L "C:\\Program Files\\vcpkg\\installed\\x64-mingw-static\\lib" -lbenchmark -lbenchmark_main -lpthread -o benchmark_test.exe

This resulted in the following errors:

collect2.exe: error: ld returned 1 exit status

My cpp is:

#include <benchmark/benchmark.h>

static void BM_StringCreation(benchmark::State& state) {
    for (auto _ : state)
        std::string empty_string;
}
BENCHMARK(BM_StringCreation);

static void BM_StringCopy(benchmark::State& state) {
    std::string x = "hello";
    for (auto _ : state)
        std::string copy(x);
}
BENCHMARK(BM_StringCopy);

BENCHMARK_MAIN();

I've ensured that the vcpkg installation is integrated with my environment and that the include paths are correct. I'm currently using g++ from the MSYS2 distribution.

Can anyone help me figure out why the linker can't find the libraries and how to properly link Google Benchmark with g++ on Windows?
