# Marks a target as only being required for tests.

#   ecm_mark_as_test(<target1> [<target2> [...]])
#
# This will cause the specified targets to not be built unless either
# BUILD_TESTING is set to ON or the user invokes the ``buildtests`` target.
#
# BUILD_TESTING is created as a cache variable by the CTest module and by the
# :kde-module:`KDECMakeSettings` module.
