GNU Radio for windows. CMake Error at CMakeLists.txt: CMAKE_C_COMPILER not set, after EnableLanguage

Question

All operations I'm doing on windows using GNU Radio Companion. Before that I downloaded CMake archive cmake-3.29.0-rc4-windows-x86_64 and wrote path to bin folder in system path variable (in cmd cmake command is working).

I dowloaded example of GRC file. It's flowgraph of the GRC file:

I attempt execute it with C++ No GUI option:

As a result, I'm getting follow error:

Generating: "D:\progs\GRC_GNURadio\dvbt_rx_demo_8k"
>>> Warning: The block 'blocks_throttle_0' is deprecated.

Executing: cmake .. && cmake --build . -j7 && cd ../.. && None -e D:\progs\GRC_GNURadio\dvbt_rx_demo_8k/build/dvbt_rx_demo_8k

-- Building for: NMake Makefiles
CMake Error at CMakeLists.txt:10 (project):
  Running

   'nmake' '-?'

  failed with:

   no such file or directory

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

>>> Done (return code 1)

Auto generated CMakeLists.txt:

cmake_minimum_required(VERSION 3.8)
set(CMAKE_CXX_STANDARD 14)

project(dvbt_rx_demo_8k)

find_package(Gnuradio "3.10" COMPONENTS
    blocks
    fec
    ... //another blocks
    soapy
)

add_executable(dvbt_rx_demo_8k dvbt_rx_demo_8k.cpp)
target_link_libraries(dvbt_rx_demo_8k
    gnuradio::gnuradio-blocks
    gnuradio::gnuradio-fft
    gnuradio::gnuradio-dtv
)

After first execution, I attempted change option Creating CMake to off and added following lines before project() function in previously (in the first execution) auto generated CMakeLists.txt:

set( CMAKE_CXX_COMPILER "/pathto/g++" )
set( CMAKE_C_COMPILER "/pathto/gcc" )

But it caused another error:

Generating: "D:\progs\GRC_GNURadio\dvbt_rx_demo_8k"
>>> Warning: The block 'blocks_throttle_0' is deprecated.

Executing: cmake .. && cmake --build . -j7 && cd ../.. && None -e D:\progs\GRC_GNURadio\dvbt_rx_demo_8k/build/dvbt_rx_demo_8k

CMake Error at CMakeLists.txt:12 (project):

   'nmake' '-?'

  failed with:

   no such file or directory


-- Configuring incomplete, errors occurred!

>>> Done (return code 1)

Then I added CXX in the end of project name in project() function. But got same error.

Executing flowgraph with Python option then execution is finished successful.
