c++ - Maven nar 构建中的 GoogleTest 编译错误 - 未定义对`testing::internal::MakeAndRegisterTestInfo 的引用

Question

我正在尝试使用 Maven 进行 Google 测试。所以，我使用这个 link 安装了它.然后我创建了用于测试的 dummyTest.cpp 并将其添加到 pom.xml 中以执行测试。当我执行 mvn clean install 时，出现以下错误 -

我使用的dummyTest.cpp、pom文件和工程结构如下:-

//
//      File:   dummyTest.cpp
//
#include "gtest/gtest.h"
TEST(dummyTest, AlwaysTrueTest) {
  EXPECT_EQ(1, 1);
}

//
//      File:   pom.xml
//

从其他博客文章和 stackoverflow 问答中，我似乎是以正确的方式来做这件事，但我无法弄清楚是什么导致了这个问题。任何帮助或任何指向正确方向的提示都将不胜感激。谢谢

请检查搜索路径中是否存在矛盾的 gtest 版本:编译期间包含的 gtest.h 是否与您链接到的库 libgtest{,_main} 所用的相同？
