Re: [CMake] Setting Policy CMP0028

2014-07-14 Thread pierre . andersson

Just to update. I managed to solve the issue by adding this line:

cmake_policy(SET CMP0028 OLD)

directly to the macro that ends up calling the add_library/add_executable
commands. Thank you for the help.

Regards,
Pierre Andersson

Given that the warning is at generation time I think it should be the
state of the policy at the end of the CMakeLists.txt that defines the
target (add_library/add_executable).

Re: [CMake] Setting Policy CMP0028

2014-07-11 Thread pierre . andersson

Then it is odd that it does not work, the warning is given during
generation time and I have tested to print the status of the 0028 policy at
all points where the projects that get the warning has their
add_library/add_executable command called, as well as at the end of their
respective CMakeLists.txt files and it remains in the state OLD throughout.
At which point is the state of the policy stored when it comes to
generation time? I can see that it works when I construct a minimal
example, so knowing when it's state is 'used' would greaty help in solving
the issue or creating a minimal example that showcases the problem.

You can not change policies for the parent; only for the current and
subdirectories.

It might help if you could create a minimal, selfcontained test case to
reproduce and debug the issue.

Thanks for the response. None of those are called in the CMakeLists.txt
file that the warning is issued for, they are both called in a file above
that one  in the build tree but said file also sets the CML0028 policy
afterwards. Is it possible that a call to cmake_minimum_required resets the
policies even for CMakeLists.txt that are not below it in the build system
tree?

Pierre Andersson

With a minimal test case the policy seems to work for me in 3.0.

What might reset the policy after it was set is:
 - A call to cmake_minimum_required()
 - A call to cmake_policy(VERSION)

[CMake] Setting Policy CMP0028

2014-07-11 Thread pierre . andersson


I have a very large project that is built with CMake, and I'm trying to
make it work a little nicer with CMake 3. Right now we, we see everal
warnigns that policy CMP0028 is not set.

Using

cmake_policy(SET CMP0028 OLD)

does not seem to take effect. It's set at the same, top level, place where
other policies are set and these do take effect. Likewise, setting the
policy to NEW does not make CMake produce the fatal error like the
documentation says it should. What am I missing here?
