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.

Before, the closely related signatures
$<condition:true_value>
$<IF:condition,true_value,false_value>
were explained in two different sections. The former section
was badly explained, with '0' and '1' in place of the formal
parameter 'condition'.
No need to save a few characters on formal parameters.
Use this occasion to correct $<PLATFORM_ID:comp>:
the parameter is a platform_id, not a compiler_id.
CPack generator names were not used consistently
throughout the documentation, resulting in ambiguity
about what the correct name was for use with the
`cpack -G` option. With the changes in this commit, the
cpack-generators(7) page of the manual now shows the
correct names and other help pages no longer use
inconsistent or incorrect names.
Boost 1.66 and above built with `--layout=versioned` add an architecture
tag to the library file names. We already try to compute this tag
automatically when `CMAKE_CXX_COMPILER_ARCHITECTURE_ID` is available,
but that is currently not computed everywhere. Add an explicit
`Boost_ARCHITECTURE` option that a user can set to specify the
architecture tag.
Issue: #17701
Ext and External were used inconsistently in the code and the
docs. This change converts all uses of Ext to External, including
within variable names used by the generator.
Minor rewording around the updated link and extra blank line
added to improve readability and remove a potential
ambiguity around the same area.
Fixes: #18545
