Unable to run rez on windows

Hi,

Can anyone tell me how to run rez on windows...?
I tried all the ways to run rez
* Followed rez wiki documentation
* installed cmake
* installed G++ compiler
but still I'm getting issue while running rez

I got this below error while building default "hello-world" package even after setting environmental path for gcc compiler
```
Executing: f:\projects\cmake-3.18.0-win64-x64\bin\cmake.exe -d F:\Temp\rez-master\example_packages\hello_world -Wno-dev -DCMAKE_ECLIPSE_GENERATE_SOURCE_PROJECT=TRUE -D_ECLIPSE_VERSION=4.3 --no-warn-unused-cli -DCMAKE_INSTALL_PREFIX=c:\users\sunil kumar nerella\packages\hello_world\1.0.0 -DCMAKE_MODULE_PATH=%CMAKE_MODULE_PATH% -DCMAKE_BUILD_TYPE=Release -DREZ_BUILD_TYPE=local -DREZ_BUILD_INSTALL=1 -G NMake Makefiles

CMake Error in CMakeLists.txt:
The CMAKE_C_COMPILER:

cl

is not a full path and was not found in the PATH.

To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat).

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.

Please help me with this. Its very difficult to use REZ on windows

Thanks

The report names the default example_packages/hello_world build and shows the CMake invocation using the NMake generator, but it names no repository file or test. Start by reproducing that Windows build with the documented setup and inspect how Rez selects CMake and the compiler environment. Done would require a confirmed Windows fix or clear documentation of the supported compiler setup.
