# vcpkg_buildpath_length_warning
|
|
|
|
Warns the user if their vcpkg installation path might be too long for the package they're installing.
|
|
|
|
```cmake
|
|
vcpkg_buildpath_length_warning(<N>)
|
|
```
|
|
|
|
`vcpkg_buildpath_length_warning` warns the user if the number of bytes in the
|
|
path to `buildtrees` is bigger than `N`. Note that this is simply a warning,
|
|
and isn't relied on for correctness.
