BUG: fix progress for ENCLUDE_FORM_ALL cases using new project to target map. Only fixes it for the top level all target

ENH: Added KWSYSPE_DEBUG macro to print debugging trace information.  Added TODO comment explaining why process execution can still hang when a grandchild keeps the output pipes open.

ENH: Merging branch PVEE-ERDC-Setup-4-3-2007 to main tree. Changes between PVEE-ERDC-Setup-4-3-2007-bp and PVEE-ERDC-Setup-4-3-2007-mp1 are included.

BUG: When a non-cache variable is marked as advance do not use the cmMakefile implementation of AddCacheDefinition to avoid removing the makefile definition.

ENH: this variable overrides all PROJECT_URL. Check the dashboard, all projects have the wrong URL in their "Home" button. Other variables (like ROLLUP_URL) were moved a while ago, for some reasons this one is still here.

BUG: The ALL_BUILD target should not have any command lines so that it is not always considered out of date.  Moved the 'Build all projects' message into the description field instead of an echo in the command field.  Moved common implementation of Generate for VS6 and VS7 into the superclass to avoid duplicate code for the ALL_BUILD target.  This addresses bug#4556.

ENH: Added option CMAKE_INSTALL_SO_NO_EXE on linux to choose whether the default permissions for shared libraries include the executable bit.  This is necessary to support the conflicting policies of Debian and Fedora.  These changes address bug#4805.
