I've been trying to use libintl with my CMake based project in Visual Studio on Windows, and was frustrated by the fact that it didn't seem to set the Intl_LIBRARIES variable, so I did some digging.

Proposed solution
It seems that the FindIntl.cmake that's shipping with vcpkg's gettext package doesn't look for the correct library name. find_library(Intl_LIBRARY "intl" DOC "libintl libraries (if not in the C library)") doesn't find the library, because it is called libintl.

Describe alternatives you've considered
I can work around this by adding find_library(Intl_LIBRARY NAMES libintl intl) before the find_package(Intl) command, but a better fix would surely be to do this in FindIntl.cmake itself.
