 Localisation is supported on a UNIX-like platform:  Linux, MacOS-X, Cygwin and MinGW/msys2.  Localisation is not supported for Visual Studio builds.
 
-To build localisation support, use the CMake option **`-DEXIV2_BUILD_PO=On`**. There are no additional build steps as the normal build commands will compile the library, samples and localisation support.  You must install the build to ensure the localisation message files can be found at run-time.
