usage: pybind11-config [-h] [--version] [--includes] [--cmakedir] [--pkgconfigdir]
                       [--extension-suffix] [--cflags] [--ldflags] [--embed] [--file FILE]

options:
  -h, --help          show this help message and exit
  --version           Print the version and exit.
  --includes          Include flags for both pybind11 and Python headers.
  --cmakedir          Print the CMake module directory, ideal for setting -Dpybind11_ROOT in
                      CMake.
  --pkgconfigdir      Print the pkgconfig directory, ideal for setting $PKG_CONFIG_PATH.
  --extension-suffix  Print the extension for a Python module
  --cflags            Print the compile flags for a simple extension (Unix-style compilers).
  --ldflags           Print the link flags for a simple extension (Unix-style compilers).
  --embed             Build for embedding instead of an extension; affects --ldflags and --file.
  --file FILE         Print a full command-line suffix for compiling the given file; the output
                      goes next to the source file (Unix-style compilers).
