By default, CMake's model is that a build directory only contains a single configuration, be it Debug, Release, MinSizeRel, or RelWithDebInfo. Of course there's no difference between files. Perhaps a set() on these variables with CMake will help under that build system. cmake --build . I know I can generate RelWithDebInfo builds, and get symbols in those, but I want symbols in the Release builds as well. If you must test the value in string comparisons, always convert the value to upper or lowercase first and adjust the test accordingly. Note that when you install a CMake project via cmake --install, you can provide the --strip argument that will strip everything upon installation. bb: SRCBRANCH = "master" SRCREV = "master" MY_SRC = " In order to build with prefixed symbols, the BORINGSSL_PREFIX CMake variable should specify the prefix to add to all symbols, and the BORINGSSL_PREFIX_SYMBOLS CMake variable should specify the path to a file which contains a list of symbols which should be prefixed (one per line; comments are supported with #). */\1/g'` But I'm not sure I can do that with CMake.
