Review Comment:
Sorry. We need `REGEX`:
```suggestion
string(REGEX REPLACE "-flto[^ ]*" "" AWS_LC_C_FLAGS "${AWS_LC_C_FLAGS}")
```
But there is another error:
```text
** testing if installed package can be loaded from temporary location
Error: package or namespace load failed for ‘arrow’ in dyn.load(file,
