[macOS] Installation of libcachesim fails

[laustam]

Bug description

The installation script install_libcachesim.sh fails to execute due to too many errors being emitted:

fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.

After brief inspection, it seems that the cause of these errors is due to clang being stricter than gcc. For example, the following errors occur frequently:

Errors generated

1. Missing newline at end of a file

error: no newline at end of file [-Werror,-Wnewline-eof]

2. Missing explicit type casting (caught by Clang with -Wformat-pedantic)

error: format specifies type 'void *' but the argument has type 'char *' [-Werror,-Wformat-pedantic]

3. Token pasting with empty VA_ARGS (not allowed by Clang)

error: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Werror,-Wgnu-zero-variadic-macro-arguments]

4. Unused private field

error: private field 'vtime_granularity_' is not used [-Werror,-Wunused-private-field]

5. Missing namespace (Clang wants explicit std::move instead of move)

error: unqualified call to 'std::move' [-Werror,-Wunqualified-std-cast-call]

Reproduction steps

1. Run bash install_libcachesim.sh as mentioned in the setup section of the README

There are two potential fixes that I can suggest:

1. Specify more permissive compiler flags for Darwin systems
2. Make changes to project files to satisfy Clang's stricter guidelines

It would be good to keep the strict compiler flags unless they cause unwanted behavior. Do you want to take a crack at fixing them?
