symbol(s) not found for architecture arm64 while writing unit tests through Google Test library on M1 Chip

I am developing a project in C++ and writing unit tests and using Google Test library for the same. I am on a MacBook Pro with M1 Chip. I installed Google Test through homebrew. On homebrew GTest page, it's mentioned that Gtest is compatible with Apple Silicon.

Apple Silicon Big Sur ✅ I am using CLion.

Here's what my CMakeLists.txt looks like:

cmake_minimum_required(VERSION 3.19)
project(GTest)

include_directories(/opt/homebrew/Cellar/googletest/1.10.0/include)
link_directories(/opt/homebrew/Cellar/googletest/1.10.0/lib)
set(CMAKE_CXX_STANDARD 14)

add_executable(GTest main.cpp)

target_link_libraries(GTest libgmock_main.a)

Do I need a .dylib for this to work on arm64? I was trying to link the libpq static library a while back and it gave me the same linking error. Then I tried to link .dylib instead of .a and it worked on arm64. But I don't see a dynamic library for GTest in lib directory.

Here are all the libraries that are there after installing GTest through homebrew:

• libgmock_main.a
• libgtest_main.a
• libgmock.a
• libgtest.a

The linking error I am getting is:

Here's the simple code that I wrote to test Google Test:

#include <iostream>
#include <gtest/gtest.h>
using namespace std;

string getStr(string str)
{
    return "1";
}

TEST(TestGetStr, First)
{
    ASSERT_STREQ("2", getStr("Arun").c_str());
}

int main()
{
    ::testing::InitGoogleTest();
    return RUN_ALL_TESTS();
}
