## # vcpkg_copy_pdbs
##
## Automatically locate pdbs in the build tree and copy them adjacent to all DLLs.
##
## ## Usage
## ```cmake
## vcpkg_copy_pdbs()
## ```
##
## ## Notes
## This command should always be called by portfiles after they have finished rearranging the binary output.
##
## ## Examples
##
## * [zlib](https://github.com/Microsoft/vcpkg/blob/master/ports/zlib/portfile.cmake)
## * [cpprestsdk](https://github.com/Microsoft/vcpkg/blob/master/ports/cpprestsdk/portfile.cmake)
