How to build c++ project with make when tests fail

I'm using cmake for build configuration and gtests as testing framework. Currently make fails if tests fail and running ctest or make test after successful build says "No tests were found!!!". I would like to be able to build project even if some tests are failing and to run tests with ctest/make test command

My CMakeLists.txt (tests added at the end of file):

    cmake_minimum_required(VERSION 3.10.0)
    project(ExampleProject VERSION 0.1.0)
    add_subdirectory("${PROJECT_SOURCE_DIR}/src/models")
    add_subdirectory("${PROJECT_SOURCE_DIR}/src/logic")
    add_subdirectory("${PROJECT_SOURCE_DIR}/src/executable")
    include(CTest)
    enable_testing()
    set(CMAKE_CXX_STANDARD 11)
    set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY build)
    set(CMAKE_LIBRARY_OUTPUT_DIRECTORY build)
    set(CMAKE_RUNTIME_OUTPUT_DIRECTORY build)
    set(CPACK_PROJECT_NAME ${PROJECT_NAME})
    set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
    include(CPack)
