detail how to build Google Mock without CMake. To make it work for Google Mock you will need to change
target_link_libraries(example gtest_main)
to
target_link_libraries(example gmock_main)
This works because `gmock_main` library is compiled with Google Test.
However, it does not automatically add Google Test includes.
Therefore you will also have to change
if (CMAKE_VERSION VERSION_LESS 2.8.11)
include_directories("${gtest_SOURCE_DIR}/include")
endif()
to
if (CMAKE_VERSION VERSION_LESS 2.8.11)
include_directories(BEFORE SYSTEM
"${gtest_SOURCE_DIR}/include" "${gmock_SOURCE_DIR}/include")
else()
target_include_directories(gmock_main SYSTEM BEFORE INTERFACE
"${gtest_SOURCE_DIR}/include" "${gmock_SOURCE_DIR}/include")
endif()
This will addtionally mark Google Mock includes as system, which will
silence compiler warnings when compiling your tests using clang with
`-Wpedantic -Wall -Wextra -Wconversion`.
