Use cmake_policy(GET) to check the policy value right before the call
to link_directories. The code in question looks like this:
switch (this->Makefile->GetPolicyStatus(cmPolicies::CMP0015))
{
case cmPolicies::WARN:
e << policies->GetPolicyWarning(cmPolicies::CMP0015);
this->Makefile->IssueMessage(cmake::AUTHOR_WARNING, e.str());
case cmPolicies::OLD:
// OLD behavior does not convert
break;
...
}
so if it is warning then we can be fairly sure the command does not
see your setting.
Note that any call to cmake_minimum_required(VERSION ...) will reset
all policies to the defaults for the specified version. If that comes
after your call to cmake_policy(SET) then it will erase your setting.
