Here's what I did and you can adjust as necessary. I downloaded gtest-1.6.0.zip (from the releases page) on my Linux box into ~/Downloads which typed out fully is /home/me/Downloads/

Unzip the contents of gtest-1.6.0.zip into ~/Downloads/gtest-1.6.0/

cd /home/me/Downloads
unzip gtest-1.6.0.zip

Build the gtest library because it's something you need to "include" in your test executable. Compile the object file gtest-all.o:

g++ -Igtest-1.6.0/include -Igtest-1.6.0 -c gtest-1.6.0/src/gtest-all.cc

Then build the library archive libgtest.a:

ar -rv libgtest.a gtest-all.o

Now you can create your test.cc file in ~/Downloads. Here is an example test file that I used to make sure it compiles.

#include "gtest/gtest.h"

TEST(blahTest, blah1) {
    EXPECT_EQ(1, 1);
}

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

    int returnValue;

    //Do whatever setup here you will need for your tests here
    //
    //

    returnValue =  RUN_ALL_TESTS();

    //Do Your teardown here if required
    //
    //

    return returnValue;
}

To compile your own test and run it:

g++ -I/home/me/Downloads/gtest-1.6.0/include -pthread test.cc libgtest.a -o test_executable

Then to execute it:

./test_executable

And it should run fine. Modify as necessary from there.
