Setup

• Windows 10 17134.48 x64
• Visual Studio 2017 15.7.1
• Toolset v14.14
• vcpkg 0.0.112
• Boost 1.67.0

Steps to Reproduce

vcpkg install boost-locale[icu]:x64-windows.

Expected Outcome

boost-locale is built with ICU support.

Actual Outcome

ICU is not detected during the build.

• The output log file states icu : no.
• config.log in the build tree states LINK : fatal error LNK1181: cannot open input file 'icudt.lib'.

There is a patch file named 0001-Fix-boost-ICU-support.patch in the boost port which seems relevant to the issue, however it is never applied. Furthermore, it is strange that the patch resides inside the boost port, and not inside boost-locale and boost-regex.
