This removes the hard-coded (and incorrect) paths to the libc++ and libc++abi

This changes the third-party Imath library from being built and linked dynamically on Windows
to being built and linked statically instead. Linux and Mac are already statically linking Imath.
Rebuilds of the third-party Alembic and OpenEXR libraries as well as the LiveCodingConsole.exe
binary were included to pick up the newly static linkage to Imath.
