* fix library exports for iconv on macOS, add Threads dependency for cairo, add the iconv, intl and Threads dependencies to harfbuzz
* updated portfile from harfbuzz fix
* fix indenting and order
* fix portfile
* [gettext] Add unofficial-gettext targets
* [gettext] Fixup for Linux
* [double-conversion] Bump to 3.1.0
This release also allows removing the workarounds for calling
vcpkg_fixup_cmake_targets twice after renaming *LibraryDepends.cmake
because upstream didn't install *Targets.cmake files. That in turn fixes
using double-conversion on Linux.
* [harfbuzz] Fix cmake configs
When building cmake with autotools, a harfbuzz-config.cmake file gets
installed that makes find_package work. However when building with
cmake, that is omitted. Therefore include a patch from upstream pull
request
https://github.com/harfbuzz/harfbuzz/pull/1161
to fix that.
* [harfbuzz] Rename targets to unofficial-harfbuzz because they are not provided by upstream
* [harfbuzz] Use Features for UCDN & Glib
Permit configuration of UCDN and Glib Unicode callback support via features.
* [harfbuzz][pango] Merge conflicts. Pango depends on harfbuzz[glib]
The needed local patches are now upstreamed thus no longer needed.
Also Uniscribe backend is no longer default enabled so almost no lib
is needed to be linked.
