Summary0015703: "cmake -E copy" support for multiple files
DescriptionThe copy operation is not support wildcart (star "*") when the full path is specified. But it is working correctly with "remove.
"cmake -E remove" is not consistent with "cmake -E copy".

With using cmake shell comamnd you could add star to whole path:
   cmake -E remove /Users/warsaw/cos/*.h

But it is not possible to make similar operation with "-E copy":
   cmake -E copy /Users/warsaw/cos/*.h ..
displays "CMakre Error"

But:
   cmake -E copy *.h ..
or:
   cmake -E copy /Users/warsaw/cos/file.h ..

is working correctly.


Steps To Reproduce1. mkdir /Users/warsaw/cos/
2. cd /Users/warsaw/cos/
3. touch file.h
4. cmake -E copy /Users/warsaw/cos/*.h ..

displays "CMakre Error"



Working correctly:
   cmake -E copy *.h ..
   cmake -E copy /Users/warsaw/cos/file.h ..

 According to the documentation:

 http://www.cmake.org/cmake/help/v3.3/manual/cmake.1.html#command-line-tool-mode [^]

The two relevant "cmake -E" signatures are:

 copy <file> <destination>

and:

 remove [-f] [<file>...]

The "remove" signature documents support for multiple files but "copy" does not. In your example the wildcard is expanded by the shell so CMake sees many arguments.

 Thanks Brad.

If wildcard is expanded by shell, then why command:
   cmake -E copy *.h ..

is working correctly.
Is should also not working, as it will be expanded by shell into multiple arguments.

 Re 0015703:0039300: If there is only one .h file then the shell wildcard will expand to just that one value as if it had been spelled out explicitly.

 Additional notes:

At Source/cmcmd.cxx there is implementation of "cmake -E" commands.
In this case the wildcard is expected to be expanded by the shell,
so what we really want is for the copy command to support multiple
inputs and a single (directory) output. The semantics should match
the UNIX "cp" command as much as possible.
