unable to build pure data version of nn~ on linux

[alexdrymonitis]

I'm trying to build nn~ on linux, but I'm stuck at this step:

cmake ../src/ -DCMAKE_PREFIX_PATH=/home/alex/Applications/libtorch -DPUREDATA_INCLUDE_DIR=/home/alex/Applications/puredata/pd-0.54-0/src -DCMAKE_BUILD_TYPE=Release

where I get the following output:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

fatal: not a git repository (or any of the parent directories): .git

Any help appreciated!

A little update here. I removed the directory and cloned from Git (I can't remember where I got the source files before, but probably not Git). It seems to build now, with the following output:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

But I can't find any executable Pd object. I'm searching my entire home directory for an nn~.pd_linux file, but there's none. Any ideas?
