# z_vcpkg_setup_pkgconfig_path
`z_vcpkg_setup_pkgconfig_path` sets up environment variables to use `pkgconfig`, such as `PKG_CONFIG` and `PKG_CONFIG_PATH`.
The original values are restored with `z_vcpkg_restore_pkgconfig_path`. `BASE_DIRS` indicates the base directories to find `.pc` files; typically `${CURRENT_INSTALLED_DIR}`, or `${CURRENT_INSTALLED_DIR}/debug`.
```cmake
z_vcpkg_setup_pkgconfig_path(BASE_DIRS <"${CURRENT_INSTALLED_DIR}" ...>)
# Build process that may transitively invoke pkgconfig
z_vcpkg_restore_pkgconfig_path()
```
