[CMake] Installing files: modification dates, directory trees

[Andy Cedilnik]

Hi David,

You can create cmake script that is run before or after installing
target, so you should be able to do whatever you want in it. So, you
could do something like:

IF(WIN32)
EXEC_PROGRAM("xcopy /p .....")
ELSE(WIN32)
EXEC_PROGRAM("cp -r ...")
ENDIF(WIN32)

That said, it is generally not a good idea to just copy the whole
directory. There can be files, directories, links, etc that you do not
want to copy. For example CVS or .svn directories. But if we would write
an install directory command, it would have to take at least a regular
expression or something of files to ignore.

I would say running a glob on directory and copy is not that hard. We do
it in several projects. This gives you full control over what to do. If
it becomes too tedious, you could always write a macro that does it.
