The old behavior of $<IN_LIST:...> is inconsistent with that of
if(IN_LIST), in that it does not find an empty search item even if
the list contains empty items. This change adds a new policy to
correctly handle empty items and make the behavior more consistent
with if(IN_LIST).

In particular, make clear that package/installer generators
are not the makefile generators of the cmake command.
Also insert sections in CPack doc, and capitalize section titles.

Removing FindQt.cmake gives Qt upstream a path forward to export its
own QtConfig.cmake files which can be found by find_package()
without having to explicitly specify CONFIG. Projects that still
want to use Qt3/4 can call find_package(Qt[34]), include(FindQt),
or add FindQt.cmake to their CMAKE_MODULE_PATH.
Remove this content from the `cmake-developer(7)` manual because it
is relevant only to developers working on CMake itself. Move it to
a guide in the developer documentation.
We no longer add granular compile features. Only language standard
meta features like `cxx_std_##`` need to be added, and these can
be done by following existing patterns.
Move deprecated or obsolete modules to the section
"Deprectated Modules" of cmake-modules(7):
- MacroAddFileDependencies (Text says: Using the macro
MACRO_ADD_FILE_DEPENDENCIES() is discouraged.)
- UsePkgConfig (Text calls it "obsolete")
- Use_wxWindows (was already listed in deprecation section)
In each environment variable doc page, insert an opening
paragraph (ENV_VAR.txt) to say that this is an environment
variable, and provide a link to the cmake-language section
on environment variables.

Section "Variables References" said that environment and cache
variables are "evaluated in the same contexts as a normal variable
reference". The reader has to guess what "contexts" means in
this context. Probably "inside a Quoted Argument or an Unquoted
Argument", exactly as for ordinary variable references.
But this is exactly what the reader would tacitly assume anyway.
Therefore I think the removed clause was unnecessary, and possibly
more confusing than helpful.
Explain that the commands affect only the current CMake process,
not the process from which CMake was called,
nor the system environment at large,
nor the environment of subsequent build or test processes.
