cmake: add workarounds for NixOS-specific deficiencies [NixOS]
|
|
|
|
The NixOS debug builder hook adds '-Wa,--compress-debug-sections' to the
|
|
link flags (it actually adds it to the compiler flags, but the compiler
|
|
is used for linking, so...). This makes the compiler angry when -Werror
|
|
is passed, because it's unused at link-time (-Wa applies to the
|
|
assembler). Suppress this warning with -Wno-unused-command-line-argument
|
|
|
|
NB: we *could* use -Wno-error=unused-command-line-argument, but that
|
|
still results in warnings anyway, just not fatal ones. We'd like to
|
|
remove them all for the sake of the build output.
