Added a missing header for macos strcasecmp

[bugdea1er]

Hi there!

I am currently using v1.5.14 as a submodule in my cmake project on macOS. I have a problem with the strcasecmp function:

.../vendor/filesystem/include/ghc/filesystem.hpp:1895:15: error: no member named 'strcasecmp' in the global namespace
return 0 == ::strcasecmp(str1, str2);
            ~~^
1 error generated.

As far as I am aware, the #include <strings.h> header is required for this function, and it is not included for the macOS build.

Or am I doing something wrong?

Sorry, it was me who was doing wrong. The simple test project works fine on macOS
