Error occur during installation of lightgbm

I am using R studio, Now i want to install LightGBM for window. I have Installed Git for Window, CMAKE and MINGW64. The path of GIT is

and the path of CMAKE is

C:\Users\MuhammadMaqsood\Downloads\cmake-3.13.3-win64-x64\bin

I have set C:\Users\MuhammadMaqsood\Downloads\cmake-3.13.3-win64-x64\bin as path for both user variable and system variable

I have run the following command for the installation of LightGbm

git clone --recursive https://github.com/Microsoft/LightGBM

cd LightGBM

mkdir build

cd build

cmake -G "MinGW Makefiles" -DUSE_OPENMP=OFF ..

mingw32-make.exe -j4

Now i have to face some two types of error.

When i set C:\Program Files\Git\bin as path for user variable and system variable then i show this error that cmake command not found.

2.when i set C:\Users\MuhammadMaqsood\Downloads\cmake-3.13.3-win64-x64\bin as path for user variable and system variable then i show this error that sh.exe found in your path even i have been delete sh.exe.

I am trying this about one month if any one has any information about this then answer me
