Ok, here is a first try in the 
ErrorIfCTEST_USE_LAUNCHERSSetButLauncherRuleNotSet branch on cmake stage.

It does now the following:
~/src/CMake/tests/ltest/b$ /opt/cmake-HEAD/bin/cmake -
DCTEST_USE_LAUNCHERS=TRUE ..
-- Configuring done
CMake Error: CTEST_USE_LAUNCHERS is enabled, but the RULE_LAUNCH_COMPILE 
global property is not defined.
Did you forget to include(CTest) in the toplevel CMakeLists.txt ?
~/src/CMake/tests/ltest/b$
