Conda CMake not finding GCC -- Windows - c++

Question

I'm running a conda environment on Windows to get a bash-similar environment (I'm a native Linux Mint user and this is my first time running Windows). But when I run cmake in my conda environment I get the following error:
-- Building for: NMake Makefiles
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:33 (project):
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've installed GCC on my conda environment, but I'm not sure how to force CMake to find it.
UPDATE:
I was able to point the compiler to where gcc is installed, but now I get this error:
