Ran: pip install opencv-python
from windows cmd with admin. First time setting up python and I don't think it's using the right environment variables
getting this error:

CMake Error at CMakeLists.txt:3 (ENABLE_LANGUAGE):
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.

I have visual studio 2019 installed, installed c++ build tools, as well as pip and wheel but it's not able to detect visual studio for some reason. I have restarted my computer after the install as well. Not sure how to resolve
