(Whoops, accidentally sent this via private email before.) My question was about this part of the example:
add_executable(consumer_with consumer_with.cpp) target_link_libraries(consumer_with foo) set_property(TARGET consumer_with CXX_STANDARD 11) add_executable(consumer_no consumer_no.cpp) target_link_libraries(consumer_no foo) The question is: how do I detect whether CXX_STANDARD 11 is available before running the "set_property(TARGET consumer_with CXX_STANDARD 11)" line? -- Daniel -----Original Message----- From: Robert Maynard [mailto:robert.mayn...@kitware.com] Sent: Wednesday, October 29, 2014 10:43 AM To: Daniel Schepler Cc: CMake MailingList Subject: Re: [CMake] [ANNOUNCE] CMake 3.1.0-rc1 now ready for testing! You can find the known compile features that can be detected at: http://www.cmake.org/cmake/help/v3.1/prop_gbl/CMAKE_CXX_KNOWN_FEATURES.html At the end of the compile-features manual page ( http://www.cmake.org/cmake/help/v3.1/manual/cmake-compile-features.7.html ) there is a section on how to mark a library as having conditional support on C++11 features.
