Always a good reason not to do it now while it still works is that by not doing it now the saved time can be used to work on other things which really need to be done now, maybe on a deadline. Once it's not working anymore it really needs to be done, and then it will be done. Yes, this postpones a problem into the future, but that's not always a bad thing.

Re: [CMake] CMP0026 - Disallow use of the LOCATION target property
Thank you Steve and NoRulez. We actually make some manipulations on the string (TEST_PATH) that returned from get_target_property, before we pass it to add_test. So if we directly pass the generator expression, it won't work. We need to change this part obviously. Any idea when CMake 4.0 is planned to release? So we can get a general idea when the old behavior will stop working.

Re: [CMake] CMP0026 - Disallow use of the LOCATION target property
Hi,
We had that problem too.
Look at the great example from Stephen to my question.
His example was great and helped us a lot.

Hi,
I have a question of policy CMP0026. Our project currently is on CMake

Lot's of questions on that lately. Someone opened the floodgates it seems
:).
When we run CMake3.1.1, we get get a few warnings due to the policy
CMP0026, Disallow use of the LOCATION target property. Even though
with those warnings, our cmake scripts still work fine and we are
getting the property correctly.
So my question is, will the support of this kind of usage be dropped
in the future releases?
Yes. That is the purpose of the policy. Attempting to read the LOCATION will
eventually be an error. That is not going to happen before CMake 4.0 though.
If we migrate away from get_target_property, $TARGET_FILE generator
expression is suggested from CMake3.1.1's documentation. So to get
the LOCATION of ${TEST_PROJECT}, I can use:
set (TEST_PATH $TARGET_FILE:${TESTS_PROJECT})
This won't work. You need to use the generator expression instead of a cmake
variable. You use the generator expression in place of ${TEST_PATH} in
add_custom_command or wherever you use it.
Thanks,
Steve.

[CMake] CMP0026 - Disallow use of the LOCATION target property
Hi,
I have a question of policy CMP0026. Our project currently is on CMake
2 and we are planning to move to CMake 3.
When we run CMake3.1.1, we get get a few warnings due to the policy
CMP0026, Disallow use of the LOCATION target property. Even though
with those warnings, our cmake scripts still work fine and we are
getting the property correctly.
One example is like this:
get_target_property (TEST_PATH ${TESTS_PROJECT} LOCATION_${CMAKE_BUILD_TYPE})
So my question is, will the support of this kind of usage be dropped
in the future releases? I understand the LOCATION property is not
fully determined until geenrate-time, however, since it works in our
case, can we rely on this behavior or we should consider it will
change in the coming 3.x releases?
If we migrate away from get_target_property, $TARGET_FILE generator
expression is suggested from CMake3.1.1's documentation. So to get
the LOCATION of ${TEST_PROJECT}, I can use:
set (TEST_PATH $TARGET_FILE:${TESTS_PROJECT})
But if I want to get LOCATION_${CMAKE_BUILD_TYPE}, how can I do it?
Thanks.
