CMakeについて(Raspberry Pi PicoのC言語開発環境構築)

Raspberry Pi PicoマイコンのC言語開発環境をWindowsに構築するために、Windowsに構築するために、https://www.zep.co.jp/nbeppu/article/z-pico-da2/

cd C:/lib/Pico/pico-examples
mkdir build
cd build
cmake -G "NMake Makefiles" ..
と進めていったのですが、
PICO platform is rp2040.
CMake Error at C:/lib/Pico/pico-sdk/cmake/preload/toolchains/find_compiler.cmake:28 (message):
Compiler 'arm-none-eabi-g++' not found, you can specify search path with
"PICO_TOOLCHAIN_PATH".

CMakeLists.txt:6 (project)

CMake Error: CMake was unable to find a build program corresponding to "NMake Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

のようなエラーが発生してしまいました。どのようにしたら、cmakeがうまくいくでしょうか？
C:\lib\Pico\pico-examples\buildのCMakeCache.txtは以下のようになっております。

# This is the CMakeCache file.
# For build in directory: c:/lib/Pico/pico-examples/build
# It was generated by CMake: C:/Program Files/CMake/bin/cmake.exe
# You can edit this file to change values found and used by cmake.
# If you do not want to change any of the values, simply exit the editor.
# If you do want to change a value, simply edit, save, and exit the editor.
# The syntax for the file is as follows:
# KEY:TYPE=VALUE
# KEY is the name of a variable in the cache.
# TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!.
# VALUE is the current value for the KEY.
