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

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:

cmake .. -G Xcode suddenly fails with the project it used to work with

I have a project, where I used to do cmake .. -G Xcode to build for Xcode and it used to work fine. I haven't touched the project for a month or so and when I ran the same command today I got an error below.
The only thing I changed since the last time I built the project was doing some Rust tutorial, so I installed some things for Rust, but I don't remember what exactly.
What could have happened?

Updating cmake to the latest version (3.18.4) resolved the problem for me.

While running cmake, `No CMAKE_ASM_COMPILER found` error

I am trying to build OpenBLAS from here, following these instructions. After running
cmake .. -G "Ninja" -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_C_COMPILER=clang-cl -DCMAKE_Fortran_COMPILER=flang -DBUILD_WITHOUT_LAPACK=no -DNOFORTRAN=0 -DDYNAMIC_ARCH=ON -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON

After a bit of googling, I found this webpage: Assembler
It does not specify how to resolve this issue. How to solve it?

Can't get CMAKE to compile a project

For the record I am using:
gcc and g++ from MinGW 4.8.1
CMake 3.4.1
I have no idea what the issue could be, I've looked extensively online and have not found anywhere where somebody has gotten a solution, except in cases where it had to do with path issues where the path included non-latin characters or no write access, which is not the case for any of the directories in question. I seriously am about to give up completely on ever being able to get this to work, but I don't know what to do because I absolutely NEED the socket.io client for C++ for this project.
CMake is a utility which generates a "makefile" for different build systems. Here you generate a nmake makefile and it seems that you don't have nmake in your path.
You can launch CMake with option -G "MinGW Makefiles" in order to generate a makefile compatible with mingw make. Then issue the command:
mingw32-make

how to get cmake to use the gnu stack of tools under msys2 (mingw)

On Windows 10, with an installed msys2, which is a variant of mingw, I have an installed cmake with the gcc toolchain and all the standard tools like make.
The version of g++ is 6.2 and make is 4.2.1 Both are in the path.
When I build using cmake:
cmake .
it tries to build using nmake and cl. So somehow because I am on windows cmake is trying to use the visual studio toolchain.
export CMAKE_CXX_COMPILER=g++
does not help. The error is:
-- Building for: NMake Makefiles
-- The C compiler identification is unknown
-- The CXX compiler identification is Clang 3.8.0

To use MSYS2 toolchain, you need to specify the build system generator explicitly, i.e.
cmake -G 'MSYS Makefiles' .
Additional note, it's a good practice to separate the application . source file and cmake's generated file, e.g.
mkdir build
cd build
cmake -G 'MSYS Makefiles' ..
