GoogleTest compilation error in Maven nar build - undefined reference to `testing::internal::MakeAndRegisterTestInfo

Question

I am trying to experiment with Google test with Maven. So, I installed it using this link. I then created dummyTest.cpp for testing and added it in pom.xml to execute the test. While I do mvn clean install, I am getting following error -

[INFO] 1 total files to be compiled.

The dummyTest.cpp, pom file and the project structure I am using is as follows :-

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

//
//      File:   pom.xml

It seems that I am doing it the right way reading from other blog posts and stackoverflow Q&A, but I could not figure out what is causing this problem. Any help or any hint towards the right direction would be highly appreciated. Thanks

Please check for contradicting versions of gtest in the search paths: Is the same gtest.h included during compilation as used for the library libgtest{,_main} you link to?
