Have you tried the various string commands?
https://cmake.org/cmake/help/v3.7/command/string.html
I’ve done something similar to replace default linker flags with ones of my own
choosing. I bet you could use something like string(REGEX REPLACE …) to
essentially remove the unwanted linker flags in each of the 5 projects that
needs it. You might even be able to do this once, in a separate .cmake file, as
either a function or macro, and then simply include() that .cmake file in each
of the 5 projects for better maintenance.

I have a CMake-based build that creates about 170 binaries (most of them
are individual unit test programs).
I have set the CMAKE_EXE_LINKER_FLAGS to a set of flags I wanted on all
the binaries.
Now it turns out that I need to remove, or not set, one specific flag on
a small number (like 5) of these binaries, but I still want it set on
all the others. Unfortunately for this flag there's no "turn it off"
extra flag I can add to the end of the list of flags: I have to actually
remove the flag itself.
What's the cleanest/simplest way to accomplish this? I don't really
want to modify my cmake files to add an explicit set_target_property()
to all 165 binaries that I _do_ want to have this flag set on, just so I
can avoid calling it on the 5 binaries I don't. I want to add something
particular to the 5 "oddball" binaries, instead, to override these
values.
But I can't seem to come up with a way to remove a flag from a global
list like this, just for one (or a few) targets.
Any hints?
