Hermes Build Error: 'O_TMPFILE' was not declared in this scope

[mengtang-pnnl]

Hermes beta 0.9.5

Both buildings with Spack and CMake have the O_TMPFILE error.
From building with Spack:

>> 309    /tmp/$USER/spack-stage/spack-stage-hermes-master-3kaezfwzoaefbzsmklylfvcesjzp4yst/spack-src/adapter/posix/fs_api.cc:24:44: error: 'O_TMPFILE' was not declared in this scope

From building with CMake:

make[1]: *** [adapter/posix/CMakeFiles/hermes_posix_backend.dir/all] Error 2
make: *** [all] Error 2

Solution for building with CMake:
Add the below lines to hermes/adapter/filesystem/filesystem.h

#ifndef O_TMPFILE
#define O_TMPFILE 0x0
#endif

Hi, @mengtang-pnnl !

Thank you for your report!
This is a known issue and a FAQ item:

@mengtang-pnnl , are you building on macOS?
If not, what's the output of uname -a?
