rigid-ipc's Issues

Unknown CMake command "rigid_ipc_download_project"

Hi, I git clone the rigid-ipc, and use python build.py to compile the project.

It gives this error:
CMake Error at python/CMakeLists.txt:6 (rigid_ipc_download_project):
Unknown CMake command "rigid_ipc_download_project".
Call Stack (most recent call first):
python/CMakeLists.txt:13 (rigid_ipc_download_pybind11)

my cmake version is 3.16.3
os: ubuntu 20.04
python: miniconda with python 3.7

BTW, I also tried with:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

This can make with no mistakes.

I think something wrong with the python part?
Any suggestions? Thanks!

Missing files or invalid fixture scripts?

I tried some of the examples in the "fixtures" directory, and the simulator works great! Nice work!

However, I discovered that there are some examples that don't run either because their mesh files don't exist in the repo or because of some other problem.

For example, this example is missing its meshes:
https://github.com/ipc-sim/rigid-ipc/blob/main/fixtures/3D/mechanisms/expanding-lock-box.json#L11-L57

This example says [2021-09-30 19:57:28.039] [error] Invalid Json file:
https://github.com/ipc-sim/rigid-ipc/blob/main/fixtures/2D/compactor.json

cmake fails on Linux Mint 19.3

Here is what I typed:

Any ideas how to fix this? It looks like a bad git reference in polysolve-src, possibly.

Thank you!
