How can I compile example in ESP-IDF - windows

Question

I've installed esp-idf and I'm trying to compile example build_system/cmake/idf_as_lib
and I got the error in the ESP-IDF CMD which not allow me to compile that example. The same problem is in Visual Studio Code.
Probably I should set environment path CMAKE_C_COMPILER but I don't know what should I point.
I've installed CMAKE on my windows
My actual environment paths:
IDF_PYTHON_ENV_PATH -> C:\esp\tools.espressif\python_env\idf4.4_py3.8_env\Scripts\python.exe
IDF_TOOLS_PATH -> C:\esp\tools.espressif
IDF_PATH -> C:\esp\esp-idf
C:\esp\esp-idf\examples\build_system\cmake\idf_as_lib>idf.py build
Executing action: all (aliases: build)
Running cmake in directory c:\esp\esp-idf\examples\build_system\cmake\idf_as_lib\build
Executing "cmake -G Ninja -DPYTHON_DEPS_CHECKED=1 -DESP_PLATFORM=1 -DCCACHE_ENABLE=1 c:\esp\esp-idf\examples\build_system\cmake\idf_as_lib"...
-- The C compiler identification is unknown
CMake Error at CMakeLists.txt:3 (project):
No CMAKE_C_COMPILER could be found.
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.
