Cmake try to find Ninja in a wrong environment of msys2

Question

I installed msys2 on Windows10 and some packages (like toolchain, cmake, ninja and others) in UCRT64 environment. I use VSCode and CMakeTools for build and run c++ projects. When I start the build process in VSCode, the process stops with errors:

[main] Configuring project: prova gtk4

CMakeLists.txt:

cmake_minimum_required(VERSION 3.10.0 FATAL_ERROR)

set(project_name "ProveGTKMM4")

project(${project_name})

set(CMAKE_CXX_STANDARD 20)

# ottengo tutti i sorgenti
file(GLOB my_sources *.cpp *.h)

# aggiungo eseguibile
add_executable(${project_name} ${my_sources})

# verifico l'esistenza delle librerie gtk4 necessarie
find_package(PkgConfig REQUIRED)
pkg_check_modules(GTKMM REQUIRED IMPORTED_TARGET gtkmm-4.0 glibmm-2.68)


# collego le librerie con l'eseguibile
target_link_libraries(${project_name} PRIVATE PkgConfig::GTKMM)

The directory "C:/msys64/ucrt64/bin" is in the environment variable PATH, unlike "C:/msys64/mingw64/bin". In the environment variable PATH there is the directory "C:/msys64/usr/bin" too. Moreover, I had installed the packages in MINGW64 environment before I installed the same packages in UCRT64 environment.

I want to force Cmake to find Ninja in directory "C:/msys64/ucrt64/bin".
