CMP0178ΒΆ
Added in version 3.31.
Test command lines preserve empty arguments.
Empty values in the TEST_LAUNCHER and
CROSSCOMPILING_EMULATOR target properties are now preserved
for tests added by the following:
The
add_test()command.The
ExternalData_Add_Test()command from theExternalDatamodule.The
gtest_add_tests()orgtest_discover_tests()commands from theGoogleTestmodule.
For the gtest_add_tests() and gtest_discover_tests()
commands, empty elements in the values passed after the EXTRA_ARGS
keyword are also now preserved.
The OLD behavior of this policy silently discards empty list items
from the TEST_LAUNCHER and CROSSCOMPILING_EMULATOR
target properties in the above-mentioned cases. It also silently discards
empty items from the values given after EXTRA_ARGS for the
gtest_add_tests() and gtest_discover_tests() commands.
The NEW behavior of this policy preserves empty list items in the
TEST_LAUNCHER and CROSSCOMPILING_EMULATOR target
properties, and in values given after EXTRA_ARGS for
gtest_add_tests() and gtest_discover_tests().
This policy was introduced in CMake version 3.31.
It may be set by cmake_policy() or cmake_minimum_required().
If it is not set, CMake warns, and uses OLD behavior.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
