# vcpkg_add_to_path
|
|
|
|
Add a directory or directories to the PATH environment variable
|
|
|
|
```cmake
|
|
vcpkg_add_to_path([PREPEND] [<path>...])
|
|
```
|
|
|
|
`vcpkg_add_to_path` adds all of the paths passed to it to the PATH environment variable.
|
|
If PREPEND is passed, then those paths are prepended to the PATH environment variable,
|
|
so that they are searched first; otherwise, those paths are appended, so they are
|
|
searched after the paths which are already in the environment variable.
|
|
|
|
The paths are added in the order received, so that the first path is always searched
|
|
before a later path.
|
|
|
|
If no paths are passed, then nothing will be done.
|
|
|
|
