[CMake] local and system installs that include python and shell scripts

[Yuri Timenkov]

I think it should be quite common case in KDE community, since GUI
usually have resources, but I don't know if apps can run from build
dir.

We use custom commands for these purposes, something like this:
         get_filename_component(destPath "${destName}" PATH)
         add_custom_command(OUTPUT ${destName}
                 MAIN_DEPENDENCY ${source}
                 COMMAND ${CMAKE_COMMAND} -E copy ${source} "${destPath}"
                 COMMENT "Copying file ${source}"
                 VERBATIM
                 )
(I don't remember if cmake can copy file with renaming or it's our legacy code)

If your scripts aren't attached to any target, you may create "custom"
one for them.

On build server you don't usually need this (because it uses install),
then you can control the behavior via special switches to allow
running locally from build directory.

I also suggest wrapping all such stuff into macros.
CMakeParseArguments helps significantly in writing macros with
informative and self-descriptive calls.
