假设目录结构为

myproject
| -- CMakeLists.txt
| -- hello_test.cpp

hello_test. cpp如下所示：

#include <gtest/gtest.h>

TEST(hello_test, add)
{
    GTEST_ASSERT_EQ((10 + 22), 32);
}

int main(int argc, char **argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

您的CMakeLists.txt应该如下所示：

cmake_minimum_required(VERSION 3.0.0)
project(myproject VERSION 0.1.0)

set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
