When I generate NMake files for a project, to build on Windows, CMAKE_CXX_FLAGS_DEBUG includes /RTC1. That's fine for most of the libraries in the build tree, but one uses /CLR and that conflicts with /RTC1. Is there a way to update the compiler flags for a particular target?
A search reveals that the out-of-tree build directory, corresponding to the target's list file directory (foo.dir), contains a flags.make with a CXX_FLAGS variable that contains /RTC1 and /CLR. I'd like to remove /RTC1 from that so the build will work. Obviously, I could change the cached CMAKE_CXX_FLAGS_DEBUG contents using SET() with FORCE, but that affects the other targets, so I'd have to add /RTC1 back for each of them. It would be much more appropriate to just subtract the flag where not wanted. I tried STRING(REPLACE) for CMAKE_CXX_FLAGS_DEBUG and CXX_FLAGS, but they don't work. I tried using GET_PROPERTY()/SET_PROPERTY() to extract, update, and write COMPILE_FLAGS for both DIRECTORY and TARGET, thinking that COMPILE_FLAGS might be the property equivalent of CXX_FLAGS. Nothing I've tried works. Any ideas? _____ Rob Stewart Software Engineer Dev Tools & Components Susquehanna International Group, LLP ________________________________ IMPORTANT: The information contained in this email and/or its attachments is confidential.
