Modify CMakeLists.txt for googletests in order to use googlemock

I was checking the quickstarter to use googletest with cmake. I was wondering how I should modify the CMakeLists.txt they provide (given below) in order to use googlemock.

cmake_minimum_required(VERSION 3.14)
project(my_project)

# GoogleTest requires at least C++14
set(CMAKE_CXX_STANDARD 14)

include(FetchContent)
FetchContent_Declare(
  googletest
  URL https://github.com/google/googletest/archive/03597a01ee50ed33e9dfd640b249b4be3799d395.zip
)
# For Windows: Prevent overriding the parent project's compiler/linker settings
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)
enable_testing()

add_executable(
  hello_test
  hello_test.cc
)
target_link_libraries(
  hello_test
  GTest::gtest_main
)

include(GoogleTest)
gtest_discover_tests(hello_test)

for the moment, #include <gtest/gtest.h> works but #include <gmock/gmock.h> doesn't

Solution

  • GMock should be available via GTest::gmock cmake target. At least this is the target name used in the cmake configuration files of a GTest build installed via cmake.

    target_link_libraries(
    hello_test
    GTest::gmock
)
