From 80ca9c4b41ecdce069a6c3f4c1b558084a748876 Mon Sep 17 00:00:00 2001 From: Stephen Kelly Date: Thu, 16 May 2013 15:15:28 +0200 Subject: Add COMPILE_OPTIONS target property. This method reads generator expressions from the COMPILE_OPTIONS target property, as well as INTERFACE_COMPILE_OPTIONS from linked dependents. --- Source/cmGeneratorExpressionDAGChecker.cxx | 8 ++ Source/cmGeneratorExpressionDAGChecker.h | 1 + Source/cmGeneratorExpressionEvaluator.cxx | 9 +- Source/cmLocalGenerator.cxx | 8 ++ Source/cmTarget.cxx | 224 +++++++++++++++++++++++++++++ Source/cmTarget.h | 4 + Tests/CMakeLists.txt | 1 + Tests/CompileOptions/CMakeLists.txt | 16 +++ Tests/CompileOptions/main.cpp | 11 ++ Tests/CompileOptions/other.cpp | 5 + 10 files changed, 286 insertions(+), 1 deletion(-) create mode 100644 Tests/CompileOptions/CMakeLists.txt create mode 100644 Tests/CompileOptions/main.cpp create mode 100644 Tests/CompileOptions/other.cpp diff --git a/Source/cmGeneratorExpressionDAGChecker.cxx b/Source/cmGeneratorExpressionDAGChecker.cxx index 5cb50b9..e5ffb0c 100644 --- a/Source/cmGeneratorExpressionDAGChecker.cxx +++ b/Source/cmGeneratorExpressionDAGChecker.cxx @@ -168,3 +168,11 @@ bool cmGeneratorExpressionDAGChecker::EvaluatingCompileDefinitions() const || strcmp(prop, "INTERFACE_COMPILE_DEFINITIONS") == 0 || strncmp(prop, "COMPILE_DEFINITIONS_", 20) == 0);
