Hello,
I am encountering a build error when trying to compile for a Alpine distribution with musl-libc.

Host Environment
    OS: alpine-3.14
    Compiler: gcc10 (10.3.1) on amd64
    Musl: musl-1.2.2-r3 (from apk info)

To Reproduce
Simply try to compile a file that includes <png++/png.hpp>

Failure logs

/tmp/build_alpine/vcpkg_installed/x64-linux/include/png++/config.hpp:63:2: error: #error Byte-order could not be detected.
   63 | #error Byte-order could not be detected.

Additional context
The problem seems to be in the config.hpp file of the png++ library.
There are several checks on the used std libraries to determine the endianness of the system but the musl library is not included, so the check fails.


Thanks for the support
