Older CMake (for example 2.8.12.2) generates feature check with unused variable, which reports false positive fail due to -Werror=unused-value. The feature is present and works, so we should only ignore this build warning. Fixes #2791. JerryScript-DCO-1.0-Signed-off-by: Csaba Osztrogonác csaba.osztrogonac@h-lab.eu
