I see some case confusion here. Is there a `metis` path that is not a directory around?

There might be some case confusion, but not of my making. It’s interesting that the error message refers to …/CMakeTmp/something, but there is nothing in CMakeTmp now, it has been erased.
Here’s a picture of the whole directory.
/metis has GKlib under it. In /build/CMakeFiles/CMakeCache.txt it states:
```auto
//path to GKlib
GKLIB_PATH:PATH=METIS/GKlib
```
Should that be edited to metis/GKlib ?
But in CMakeLists.txt there is:
```auto
cmake_minimum_required(VERSION 2.8)
project(ParMETIS)
set(GKLIB_PATH METIS/GKlib CACHE PATH "path to GKlib")
set(METIS_PATH METIS CACHE PATH "path to METIS")
# Symlink ./metis to wherever metis is. This allows files to be
# included from metis/libmetis/.
execute_process(COMMAND ${CMAKE_COMMAND} -E create_symlink ${METIS_PATH} metis)
```
Thanks for any and all assistance, it is greatly appreciated.
Edit: As a new user I cannot upload files, that’s what this site told me. It was 5.8MB zipped.

Pass `--debug-trycompile` to keep things around.

Hope I am doing this correctly
```auto
% cmake . -B build --debug-trycompile -DCMAKE_TOOLCHAIN_FILE=$PWD/homebrew.cmake

I really feel like this is highly relevant; can you track down what this is trying to do and what it’s supposed to do?
