# $(call copySrcDirRel,srcfile...,dir[,prefix])
#   Template to copy source files to the destination directory. Each source
#   file is copied iff the destination file does not exists or if the source is
#   newer. Subdirectories of the destination directory are created as needed.
#   If the prefix paramter is specified, string up to prefix is stripped off
#   the source files prior to copying. Otherwise the common directory part
#   between the target and source are removed.
#
#   Example 1:
#     srcfiles = share/etc/rules.d/my.rules share/etc/ld.so.conf.d/my.conf
#     etcdir   = /path/to/mypkg/dist/dist.arch/etc
#     $(call copySrcDirRel,$(srcfiles),$(etcdir) -->
#         /path/to/mypkg/dist/dist.arch/etc/rules.d/my.rules
#         /path/to/mypkg/dist/dist.arch/etc/ld.so.conf.d/my.conf
#   Example 2:
#     srcfile = share/lib/cmake/mypkg-config.cmake
#     libdir  = /path/to/mypkg/dist/dist.arch/lib
#     $(call copySrcDirRel,$(srcfile),$(libdir)) -->
#         /path/to/mypkg/dist/dist.arch/lib/cmake/mypkg-config.cmake
#   Example 3:
#     srcfiles = share/theroad share/food/cake
#     sharedir = /path/to/mypkg/dist/dist.arch/share/mypkg-x.y.z
#     $(call copySrcDirRel,$(srcfiles),$(sharedir),share) -->
#         /path/to/mypkg/dist/dist.arch/share/mypkg-x.y.z/theroad
