An example is the GNU MPC library: its C header files refer to those of

This field is like @code{inputs}, but the specified packages will be
force-installed alongside the package they belong to. For example this
is necessary when a library needs headers of another library to compile,
or needs another shared library to be linked alongside itself when a
program wants to link to it.

This field is like @code{inputs}, but in case of a cross-compilation it

This is typically where you would list tools needed at build time but
