[CMake] Calling install() from parent directory

[Petr Kmoch]

This is unfortunately not possible. In a nutshell, my setup is as follows:

## top_level/CMakeLists.txt:
set_property(GLOBAL PROPERTY my_project_list
${variable_defined_on_command_line})

get_property(projects GLOBAL PROPERTY my_project_list)
while(projects)
  set_property(GLOBAL PROPERTY my_project_list "")
  foreach(proj IN LISTS projects)
    add_subdirectory(${proj}) # this can add projects to
my_project_list global property and/or modify my_istallations global
property
  endforeach()
endwhile()

install(TARGETS ${some_targets_defined_in_subdirectories} DESTINATION
${something_which_depends_on_global_property_my_installations})
##

As a workaround, I am currently using install(PROGRAMS
path_to_target's_output ...), but if there is a way to use the actual
target, I would prefer it.
