After some more research:
Enabling LTO will actually cause the compiler to only produce thin LTO by adding
`-flto -fno-fat-lto-objects` to the compiler options. I am not sure this is an ideal choice
because if an application linking against the FSFW does not use LTO, there can be compile
issues (e.g. observed when compiling the FSFW tests without LTO). This is a known issue as
can be seen in the multiple CMake issues for it:
- https://gitlab.kitware.com/cmake/cmake/-/issues/22913,
- https://gitlab.kitware.com/cmake/cmake/-/issues/16808,
- https://gitlab.kitware.com/cmake/cmake/-/issues/21696
Easiest solution for now: Keep this option OFF by default.
