-Add a directory to the PATH environment variable
+Add a directory or directories to the PATH environment variable
-## Usage
```cmake
-vcpkg_add_to_path([PREPEND] <${PYTHON3_DIR}>)
+vcpkg_add_to_path([PREPEND] [<path>...])
```
-## Parameters
-### <positional>
-The directory to add
+`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.
-### PREPEND
-Prepends the directory.
+The paths are added in the order received, so that the first path is always searched
+before a later path.
-The default is to append.
+If no paths are passed, then nothing will be done.
