CMake: Build third-party deps in Windows

- Update recipes to build with MSVC or cross compile in Unix with Mingw
- For recipes that need to be reused, wrap recipe in CMake function
  using cmake_parse_arguments
- New directory .deps/host is the install root for HOST targets, the old
  .deps/usr is used for TARGET
- In windows disable builds for terminal libraries and jemalloc
- Added cmake script CopyFilesGlob.cmake to copy files using glob
    cmake -DFROM_GLOB=*.h -DTO=/usr/include -P CopyFilesGlob.cmake
- New CMake variables HOSTDEPS_* can be used in cross compile recipes.
  Except when the target is UNIX, since that would break 32bit builds
  in 64bit Unix systems using the Travis 32bit toolchain
