Emscripten can't find path to cmake

I've gone over the instructions several times, looked in countless forums, and still can't resolve this issue.

I'm running Windows 10, and simply trying to install Emscripten. I've got Emscripten installed:

I run

# Fetch the latest registry of available tools.
emsdk update

followed by

# Download and install the latest SDK tools.
emsdk install latest

But it continues to throw the same warning about being unable to find the path to cmake.

I've downloaded and installed cmake-3.3.2-win32-x86. I cannot create the PATH from the installation though, because it says the file length is too long. odd, because it is installed here:

C:\Program Files (x86)\CMake\bin

I figured I could set the path myself, as seen in this SO post. Therefore, I used this command after the image above:

set PATH="C:\Program Files (x86)\CMake\bin\";%PATH%

and have the same issue. I'm fresh out of ideas.
