By default, the cmake derivation contains the documentation in .rst
format. This format is not well suited for interactive use. Therefore,
we add both man and info outputs and convert the documentation to
these formats using Sphinx.
These formats are enabled by default only in cmake versions for
interactive use (ncurses, Qt), because using Sphinx in the basic
version leads to circular dependency (infinite recursion). Namely,
Sphinx has imagemagick in its checkInputs and imagemagick has several
transitive dependencies, which have cmake in nativeBuildInputs.
This `substituteInPlace` was introduced in 2016 when cmake was at v3.4:
* https://github.com/NixOS/nixpkgs/commit/5286c0aebb
In 2018 cmake v3.12.0 changed the code to make it not match anything:
* https://github.com/Kitware/CMake/commit/50b5e9ed13
```
substituteStream(): WARNING: pattern '${PYTHON_EXECUTABLE}' doesn't match anything in file 'Modules/FindCxxTest.cmake'
```
Having it around in 2021 with cmake v3.19.3 doesn't help,
and tests are disabled anyway.

pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
This fixes issues with building LibreSSL, which is required for the
NixOS tests: https://cmake.org/cmake/help/latest/release/3.19.html#id1

This reverts commit c778945806.
I believe this is exactly what brings the staging branch into
the right shape after the last merge from master (through staging-next);
otherwise part of staging changes would be lost
(due to being already reachable from master but reverted).
- OpenSSL is evidentally an optional dep. I guess pkg-config found it
before because it was a transitive dep?
- `zstd` and cross-built CMake can get by with a `cmakeMinimal that we
use during bootstrapping, so let's restrict to that.
pkg-config now has a target-sensative wrapper. We shouldn't rebuild
CMake because that wrapper changes. The setup hook should also be a
build time dep.
Fix#99325
I hate the thing too even though I made it, and rather just get rid of
it. But we can't do that yet. In the meantime, this brings us more
inline with autoconf and will make it slightly easier for me to write a
pkg-config wrapper, which we need.
cf-private is not necessary here. cmake just needs the CoreFoundation
framework to be used. swift-corefoundation seems to work fine in this case.
