CMake fails to determine the bitness of the target platform

When running npm install, the install hits the following line and takes a very long time to find the compiler:
-- The CXX compiler identification is AppleClang 11.0.3.11030032
-- The C compiler identification is AppleClang 11.0.3.11030032
-- Check for working CXX compiler: /Applications/Xcode.app/Contents/

It slowly steps through the next few lines, and eventually fails at CMake. I'm not familiar with C++ dev and was having a difficult time finding documentation for debugging CMake to try and diagnose the issue further. Any help would be appreciated.

CMake Error at CMakeLists.txt:153 (message):
CMake fails to determine the bitness of the target platform.

Please check your CMake and compiler installation. If you are cross-compiling then ensure that your CMake toolchain file correctly sets the compiler details.
