CMAKE_EXE_LINKER_FLAGS_INIT is a bit special. You have to specify it on
the first CMake run you do for a project (ie: before the CMakeCache.txt
file has been created), and whatever you put in it will be added to
whatever default value for CMAKE_EXE_LINKER_FLAGS that CMake comes up
with (which I believe is just the contents of the LDFLAGS env var when
compiling with Clang or GCC). After that, it will be ignored, and you'll
want to modify CMAKE_EXE_LINKER_FLAGS directly.
Note that what I said above only applies to setting this variable on the
command line, not to setting it from within CMake code (when you'll just
want to append to CMAKE_EXE_LINKER_FLAGS).
I'm not sure what you mean by "incremental", though. All CMake variables
overwrite their previous values when you set them, so you have to
explicitly include the old value when you set them, and you can't really
do this from the command line.
