From 97fae68b81d7dbb5dda9fe21f860863bcc0c7183 Mon Sep 17 00:00:00 2001 From: Stephen Kelly Date: Tue, 10 Dec 2013 17:16:08 +0100 Subject: Remove INTERFACE build targets. Commit b04f3b9a (Create make rules for INTERFACE_LIBRARY targets., 2013-08-21) extended the makefile generator to create build targets for INTERFACE_LIBRARY targets. No other generators were extended with this feature. This conflicts with the feature of whitelisting of target properties read from INTERFACE_LIBRARY targets. The INTERFACE_* properties of the INTERFACE_LIBRARY may legitimately contain TARGET_PROPERTY generator expressions for reading properties from the 'head target'. The 'head target' would be the INTERFACE_LIBRARY itself when creating the build rules for it, which means that non-whitelisted properties would be read. --- Source/cmComputeTargetDepends.cxx | 25 +++----- Source/cmGlobalUnixMakefileGenerator3.cxx | 92 ++++++++++++----------------- Source/cmLocalUnixMakefileGenerator3.cxx | 1 - Source/cmMakefileLibraryTargetGenerator.cxx | 3 - Source/cmMakefileTargetGenerator.cxx | 1 - Tests/CMakeLists.txt | 18 ------ Tests/InterfaceBuildTargets/CMakeLists.txt | 13 ---- Tests/InterfaceBuildTargets/main.cxx | 5 -- Tests/InterfaceBuildTargets/testlib.cxx | 5 -- Tests/InterfaceLibrary/CMakeLists.txt | 14 +++++ Tests/InterfaceLibrary/broken.cpp | 2 + Tests/InterfaceLibrary/dummy.cpp | 5 ++ 12 files changed, 65 insertions(+), 119 deletions(-) delete mode 100644 Tests/InterfaceBuildTargets/CMakeLists.txt delete mode 100644 Tests/InterfaceBuildTargets/main.cxx delete mode 100644 Tests/InterfaceBuildTargets/testlib.cxx create mode 100644 Tests/InterfaceLibrary/broken.cpp create mode 100644 Tests/InterfaceLibrary/dummy.cpp diff --git a/Source/cmComputeTargetDepends.cxx b/Source/cmComputeTargetDepends.cxx index cb9e37e..02fd173 100644 --- a/Source/cmComputeTargetDepends.cxx +++ b/Source/cmComputeTargetDepends.cxx @@ -199,6 +199,10 @@ void cmComputeTargetDepends::CollectTargetDepends(int depender_index) { // Get the depender. cmTarget* depender = this->Targets[depender_index];
