Setting Up Google Mock 1.6 - c++

Question

I'm trying to follow along with Modern C++ Programming with Test-Driven Development and to do so the book instructs readers to install
Google Mock 1.6. Trying to do I downloaded the source from here. Then according to the book I do:
mkdir build
cd build
cmake ..
make
myComputer:build me$ cmake ..
-- The CXX compiler identification is AppleClang 8.0.0.8000042
-- The C compiler identification is AppleClang 8.0.0.8000042
-- Check for working CXX compiler: /Library/Developer/CommandLineTools/usr/bin/c++
-- Check for working CXX compiler: /Library/Developer/CommandLineTools/usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features

CMake Error at CMakeLists.txt:56 (add_subdirectory):
add_subdirectory given source "../gtest" which is not an existing
directory.
CMake Error at CMakeLists.txt:61 (config_compiler_and_linker):
Unknown CMake command "config_compiler_and_linker".
-- Configuring incomplete, errors occurred!
See also "/Users/me/Downloads/googlemock-release-1.6.0 3/build/CMakeFiles/CMakeOutput.log".
The ../gtest directory is indeed missing. As these are the directories:
CHANGES COPYING build include scripts
CMakeLists.txt Makefile.am build-aux make src
CONTRIBUTORS README configure.ac msvc test
Adding to the confusion are these instructions:
You will also need to build Google Test, which is nested within Google Mock.
cd $GMOCK_HOME/gtest
mkdir mybuild
cd mybuild
cmake ..
make
I looked at the README and I don't seem anything that helps resolve this issue. Any help/guidance would be super!

Answer 1

As you can see here, Google Mock has been absorbed into the GoogleTest project.
There are various ways to install GoogleTest, described in The GoogleTest Readme. Since you seem to be using CMake, I suggest you follow the steps under
Incorporating Into An Existing CMake Project
You can also put everything that should go into CMakeLists.txt into CMakeLists.GTest and then only put include(CmakeLists.GTest) in CMakeLists.txt.
If you want to determine a fixed version of GoogleTest that should be incorporated, you can use the GIT_TAG eg release-1.8.0´ instead ofmaster` in your CMakeLists.txt.in.
After incorporating GoogleTest in your project, you can add gtests for class Foo by creating eg FooTest.cpp that includes gtest/gtest.h and Foo.h. Therefore, you also have to put add_executable(FooTarget FooTest.cpp) and target_link_libraries(FooTarget gtest) in the corresponding CMakeLists.txt.
You can also find a short description of this, and how to integrate GoogleTests into ctest on these slides).

You need to have gtest inside gmock dir.
I initialy had same error as you, than took gtest version 1.6 from https://github.com/google/googletest and placed it in gmock root dir and succesfully built it.
