From 2b218883cda6b16d38eb2372ab080aa5f5326e0c Mon Sep 17 00:00:00 2001 From: Brad King Date: Tue, 13 Oct 2020 14:01:54 -0400 Subject: Add deprecation warnings for policies CMP0075 and below The OLD behaviors of all policies are deprecated, but only by documentation. Add an explicit deprecation diagnostic for policies introduced in CMake 3.12 and below to encourage projects to port away from setting policies to OLD. --- Source/cmMakefile.cxx | 2 +- Tests/RunCMake/CheckModules/CMP0075-stderr.txt | 13 ++++++++++++- Tests/RunCMake/add_library/CMP0073-stderr.txt | 10 ++++++++++ 3 files changed, 23 insertions(+), 2 deletions(-) create mode 100644 Tests/RunCMake/add_library/CMP0073-stderr.txt diff --git a/Source/cmMakefile.cxx b/Source/cmMakefile.cxx index 9286e93..c366b48 100644 --- a/Source/cmMakefile.cxx +++ b/Source/cmMakefile.cxx @@ -4427,7 +4427,7 @@ bool cmMakefile::SetPolicy(cmPolicies::PolicyID id, // Deprecate old policies, especially those that require a lot // of code to maintain the old behavior. - if (status == cmPolicies::OLD && id <= cmPolicies::CMP0072 && + if (status == cmPolicies::OLD && id <= cmPolicies::CMP0075 && !(this->GetCMakeInstance()->GetIsInTryCompile() && ( // Policies set by cmCoreTryCompile::TryCompileCode. diff --git a/Tests/RunCMake/CheckModules/CMP0075-stderr.txt b/Tests/RunCMake/CheckModules/CMP0075-stderr.txt index 960fe94..97833f5 100644 --- a/Tests/RunCMake/CheckModules/CMP0075-stderr.txt +++ b/Tests/RunCMake/CheckModules/CMP0075-stderr.txt @@ -47,4 +47,15 @@ CMake Warning \(dev\) at [^ Call Stack \(most recent call first\): CMP0075.cmake:41 \(check_include_files\) CMakeLists.txt:[0-9]+ \(include\) -This warning is for project developers.
