docs: Make CMake build system default, mark GNU Make as legacy option All `-cmake` suffixes are removed Where a GNU Make option is renamed, the `-legacy` suffix is used

docs: Functional renaming commit for CMake-as-default Rename all the files which will be edited substantially in the next commit, without changing their contents Docs will not build for this ocmmit. This is done so that git doesn't decide we renamed xxx-cmake -> xxx-legacy in the next commit, which is what it will infer otherwise (and makes rebasing more of a pain than it should be)

Standard process for installing the toolchain is described :doc:`here <macos-setup>`. See :ref:`Customized Setup of Toolchain <get-started-customized-setup-legacy>` section for some of the reasons why installing the toolchain from scratch may be necessary.

Install Prerequisites
=====================
- install pip::
sudo easy_install pip

``pip`` will be used later for installing :ref:`the required Python packages <get-started-get-packages-legacy>`.

Compile the Toolchain from Source
=================================
- Install dependencies:
- Install either MacPorts_ or homebrew_ package manager. MacPorts needs a full XCode installation, while homebrew only needs XCode command line tools.
.. _homebrew: https://brew.sh/
.. _MacPorts: https://www.macports.org/install.php
- with MacPorts::
sudo port install gsed gawk binutils gperf grep gettext wget libtool autoconf automake
- with homebrew::
brew install gnu-sed gawk binutils gperftools gettext wget help2man libtool autoconf automake
Create a case-sensitive filesystem image::
hdiutil create ~/esp/crosstool.dmg -volname "ctng" -size 10g -fs "Case-sensitive HFS+"
Mount it::
hdiutil mount ~/esp/crosstool.dmg
Create a symlink to your work directory::
mkdir -p ~/esp
ln -s /Volumes/ctng ~/esp/ctng-volume
Go into the newly created directory::
cd ~/esp/ctng-volume
Download ``crosstool-NG`` and build it:

Build the toolchain::
./ct-ng xtensa-esp32-elf
./ct-ng build
chmod -R u+w builds/xtensa-esp32-elf

Toolchain will be built in ``~/esp/ctng-volume/crosstool-NG/builds/xtensa-esp32-elf``. Follow :ref:`instructions for standard setup <setup-macos-toolchain-add-it-to-path-legacy>` to add the toolchain to your ``PATH``.
