Enable CMake's built-in testing subsystem:

# For make-based builds, defines make target named test.
# For Visual Studio builds, defines Visual Studio project named RUN_TESTS.
enable_testing()

Compile an executable that will run your unit tests and link it with gtest and gtest_main:

add_executable(runUnitTests
    project1_unittests.cpp
)
target_link_libraries(runUnitTests gtest gtest_main)

Add a test which runs this executable:

add_test(
    NAME runUnitTests
    COMMAND runUnitTests
)
