* CMake sets a `RPATH` for binaries that link to a library in the the
same project. Even when this is stripped at installation time, the
build-id section will be different. Possible workarounds:
* Set `CMAKE_BUILD_WITH_INSTALL_RPATH=ON` or `CMAKE_SKIP_RPATH=ON` to
ensure a deterministic RPATH. Disadvantage: programs from the build
directory cannot be run without setting `LD_LIBRARY_PATH`.
* Users can set
[`CMAKE_SKIP_RPATH=ON`](https://cmake.org/cmake/help/latest/variable/CMAKE_SKIP_RPATH.html)
to disable the use of RPATH.
Disadvantage: programs from the build directory cannot be run without
setting `LD_LIBRARY_PATH`.

and downstream distributions.
