I have a CMake generated eclipse project. Is there any way to enable C++11 support for the indexer in this scenario (compiler flags are set in the CMakeLists.txt file and I can't find any options in the project settings to enable C++11 support).

In addition to what you did, use the "Dialect" option under Project Properties -> C++ Build -> Settings -> GCC C++ Compiler (or whatever your toolchain compiler is).

If the dialect option isn't there, add -std=c++11 to "Miscellaneous" under GCC C++ Compiler and GCC C++ Linker.

Finally, does adding the following to the main CMakeLists.txt file help at all?

if (${CMAKE_EXTRA_GENERATOR} MATCHES "Eclipse CDT4")
	add_definitions (-DCMAKE_CXX_COMPILER_ARG1=-std=c++11)
	add_definitions (-DCMAKE_ECLIPSE_GENERATE_SOURCE_PROJECT=TRUE)
endif (${CMAKE_EXTRA_GENERATOR} MATCHES "Eclipse CDT4")
