# z_vcpkg_function_arguments

Get a list of the arguments which were passed in.
Unlike `ARGV`, which is simply the arguments joined with `;`,
so that `(A B)` is not distinguishable from `("A;B")`,
this macro gives `"A;B"` for the first argument list,
and `"A\;B"` for the second.

```cmake
z_vcpkg_function_arguments(<out-var> [<N>])
```

`z_vcpkg_function_arguments` gets the arguments between `ARGV<N>` and the last argument.
`<N>` defaults to `0`, so that all arguments are taken.

## Example:
```cmake
function(foo_replacement)
    z_vcpkg_function_arguments(ARGS)
    foo(${ARGS})
    ...
endfunction()
```
#]===]

#[===[.md:
# z_vcpkg_*_parent_scope_export
If you need to re-export variables to a parent scope from a call,
you can put these around the call to re-export those variables that have changed locally
to parent scope.

## Usage:
```cmake
z_vcpkg_start_parent_scope_export(
    [PREFIX <PREFIX>]
)
z_vcpkg_complete_parent_scope_export(
    [PREFIX <PREFIX>]
    [IGNORE_REGEX <REGEX>]
)
```

## Parameters
### PREFIX
The prefix to use to store the old variable values; defaults to `Z_VCPKG_PARENT_SCOPE_EXPORT`.
The value of each variable `<VAR>` will be stored in `${PREFIX}_<VAR>` by `start`,
and then every variable which is different from `${PREFIX}_VAR` will be re-exported by `complete`.

### IGNORE_REGEX
Variables with names matching this regex will not be exported even if their value has changed.

## Example:
```cmake
z_vcpkg_start_parent_scope_export()
_find_package(blah)
z_vcpkg_complete_parent_scope_export()
```
