From fe732264e9abb6249d1d112b24ce36b226590105 Mon Sep 17 00:00:00 2001 From: Stephen Kelly Date: Fri, 2 Nov 2012 15:47:40 +0100 Subject: [PATCH] Add the INTERFACE_LIBRARY target type. This target type only contains INTERFACE_* properties, so it can be used as a structural node. The target-specific commands enforce that they may only be used with the INTERFACE keyword when used with INTERFACE_LIBRARY targets. The old-style target properties matching LINK_INTERFACE_LIBRARIES_ are always ignored for this target type. The name of the INTERFACE_LIBRARY must match a validity generator expression. The validity is similar to that of an ALIAS target, but with the additional restriction that it may not contain double colons. Double colons will carry the meaning of IMPORTED or ALIAS targets in CMake 2.8.13. An ALIAS target may be created for an INTERFACE library. At this point it can not be exported and does not appear in the buildsystem and project files are not created for them. That may be added as a feature in a later commit. The generators need some changes to handle the INTERFACE_LIBRARY targets returned by cmComputeLinkInterface::GetItems. The Ninja generator does not use that API, so it doesn't require changes related to that. --- Source/cmAddLibraryCommand.cxx | 30 ++++- Source/cmAddLibraryCommand.h | 10 ++ Source/cmComputeLinkDepends.cxx | 7 ++ Source/cmComputeLinkInformation.cxx | 5 + Source/cmGlobalGenerator.cxx | 4 + Source/cmGlobalNinjaGenerator.cxx | 7 +- Source/cmGlobalUnixMakefileGenerator3.cxx | 8 ++ Source/cmGlobalVisualStudio6Generator.cxx | 4 + Source/cmGlobalVisualStudio7Generator.cxx | 4 + Source/cmGlobalVisualStudio8Generator.cxx | 4 + Source/cmGlobalVisualStudioGenerator.cxx | 4 + Source/cmGlobalXCodeGenerator.cxx | 25 +++- Source/cmInstallTargetGenerator.cxx | 5 + Source/cmLocalGenerator.cxx | 8 ++ Source/cmLocalVisualStudio10Generator.cxx | 4 + Source/cmLocalVisualStudio6Generator.cxx | 10 +- Source/cmLocalVisualStudio7Generator.cxx | 12 +- Source/cmMakefile.cxx | 5 +- Source/cmMakefileTargetGenerator.cxx | 7 +- Source/cmTarget.cxx | 108 +++++++++++------- Source/cmTarget.h | 1 + Source/cmTargetLinkLibrariesCommand.cxx | 14 +++ Source/cmTargetPropCommandBase.cxx | 9 ++ Source/cmVisualStudio10TargetGenerator.cxx | 8 +- Tests/AliasTarget/CMakeLists.txt | 3 + Tests/CMakeLists.txt | 1 + Tests/CompatibleInterface/CMakeLists.txt | 2 +- Tests/InterfaceLibrary/CMakeLists.txt | 15 +++ Tests/InterfaceLibrary/definetestexe.cpp | 9 ++ Tests/InterfaceLibrary/libsdir/CMakeLists.txt | 26 +++++ .../libsdir/shareddependlib.cpp | 7 ++ .../libsdir/shareddependlib/shareddependlib.h | 12 ++ Tests/InterfaceLibrary/libsdir/sharedlib.cpp | 12 ++ .../libsdir/sharedlib/sharedlib.h | 15 +++ Tests/InterfaceLibrary/sharedlibtestexe.cpp | 19 +++ .../PositionIndependentTargets/CMakeLists.txt | 1 + .../interface/CMakeLists.txt | 27 +++++ Tests/RunCMake/CMakeLists.txt | 1 + .../Conflict4-result.txt | 1 + .../Conflict4-stderr.txt | 4 + .../PositionIndependentCode/Conflict4.cmake | 8 ++ .../Conflict5-result.txt | 1 + .../Conflict5-stderr.txt | 3 + .../PositionIndependentCode/Conflict5.cmake | 9 ++ .../Conflict6-result.txt | 1 + .../Conflict6-stderr.txt | 4 + .../PositionIndependentCode/Conflict6.cmake | 8 ++ .../RunCMakeTest.cmake | 3 + .../RunCMake/interface_library/CMakeLists.txt | 3 + .../interface_library/RunCMakeTest.cmake | 4 + .../interface_library/invalid_name-result.txt | 1 + .../interface_library/invalid_name-stderr.txt | 9 ++ .../interface_library/invalid_name.cmake | 4 + .../target_commands-result.txt | 1 + .../target_commands-stderr.txt | 47 ++++++++ .../interface_library/target_commands.cmake | 13 +++ 56 files changed, 528 insertions(+), 49 deletions(-) create mode 100644 Tests/InterfaceLibrary/CMakeLists.txt create mode 100644 Tests/InterfaceLibrary/definetestexe.cpp create mode 100644 Tests/InterfaceLibrary/libsdir/CMakeLists.txt create mode 100644 Tests/InterfaceLibrary/libsdir/shareddependlib.cpp create mode 100644 Tests/InterfaceLibrary/libsdir/shareddependlib/shareddependlib.h create mode 100644 Tests/InterfaceLibrary/libsdir/sharedlib.cpp create mode 100644 Tests/InterfaceLibrary/libsdir/sharedlib/sharedlib.h create mode 100644 Tests/InterfaceLibrary/sharedlibtestexe.cpp create mode 100644 Tests/PositionIndependentTargets/interface/CMakeLists.txt create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict4-result.txt create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict4-stderr.txt create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict4.cmake create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict5-result.txt create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict5-stderr.txt create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict5.cmake create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict6-result.txt create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict6-stderr.txt create mode 100644 Tests/RunCMake/PositionIndependentCode/Conflict6.cmake create mode 100644 Tests/RunCMake/interface_library/CMakeLists.txt create mode 100644 Tests/RunCMake/interface_library/RunCMakeTest.cmake create mode 100644 Tests/RunCMake/interface_library/invalid_name-result.txt create mode 100644 Tests/RunCMake/interface_library/invalid_name-stderr.txt create mode 100644 Tests/RunCMake/interface_library/invalid_name.cmake create mode 100644 Tests/RunCMake/interface_library/target_commands-result.txt create mode 100644 Tests/RunCMake/interface_library/target_commands-stderr.txt create mode 100644 Tests/RunCMake/interface_library/target_commands.cmake diff --git a/Source/cmAddLibraryCommand.cxx b/Source/cmAddLibraryCommand.cxx index cbc6ed1e9..130a033a8 100644 --- a/Source/cmAddLibraryCommand.cxx +++ b/Source/cmAddLibraryCommand.cxx @@ -82,6 +82,12 @@ bool cmAddLibraryCommand ++s;
