+Tests are only built when googletest is found.
 
 The `<spirv-build-dir>/UnitSPIRV` executable runs the project tests.
 It supports the standard `googletest` command line options.
 
+The project also adds a CMake test `spirv-tools-testsuite`, which executes
+`UnitSPIRV`.  That way it's possible to run the tests using `ctest`.
