Hi, I am on ubuntu20.04. I wonder what is your CMakeLists.txt look like? Do you have ant test cases?
I spent hours but could not get gtest working by trying many tricks.

Hello! I've just tested this Gist on Ubuntu 20.04 and I got successful results.
Use this as an example CMakeLists.txt

cmake_minimum_required(VERSION 3.5)

project(example LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(GTest REQUIRED)
include_directories(${GTEST_INCLUDE_DIRS})

add_executable(example main.cpp)
target_link_libraries(example ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES})

and main.cpp

#include <gtest/gtest.h>

TEST(test_case, example_test)
{
    EXPECT_EQ(2, 2);
}

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

  1. gist script will clone Gtest source code, build it, install it in default Ubuntu libraries directory
  2. the project specific CMakeLists.txt will set Gtest as required library (it will look in the above mentioned Ubuntu directory) and link the public headers to your project executable
  3. in main.cpp Gtest header is imported and used in the example test
    let me know if it was clear:)

Not sure why but for me it did not work with the share lib flag.

So what I did was (note the -DBUILD_SHARED_LIBS=OFF):

git clone https://github.com/google/googletest.git

cd googletest
mkdir build && cd build

cmake .. -GNinja -DBUILD_SHARED_LIBS=OFF -DINSTALL_GTEST=ON -DCMAKE_INSTALL_PREFIX:PATH=/usr
cmake --build .
sudo cmake --install .
sudo ldconfig

...furthermore my CMakeLists.txt looks a little different, as I took the one from the official CMake documentation (https://cmake.org/cmake/help/v3.6/module/FindGTest.html) :

enable_testing()
find_package(GTest REQUIRED)

add_executable(foo foo.cc)
target_link_libraries(foo GTest::GTest GTest::Main)

add_test(AllTestsInFoo foo)
