build_cuda102.sh

#!/bin/bash -e
#
# This is a build script for DSP-SLAM.
#
# Use parameters:
# `--install-cuda` to install the NVIDIA CUDA suite
#
# Example:
#   ./build_cuda102.sh --install-cuda --build-dependencies --create-conda-env
#
#   which will
#   1. Install some system dependencies
#   2. Install CUDA-11.3 under /usr/local
#   3. Create and build:
#   - ./Thirdparty/opencv
#   - ./Thirdparty/eigen
#   - ./Thirdparty/Pangolin
#   4. Build:
#   - ./Thirdparty/g2o
#   - ./Thirdparty/DBoW2
#   5. Create conda env with PyTorch 1.10
#   6. Install mmdetection and mmdetection3d
#   7. Build DSP-SLAM

# Function that executes the clone command given as $1 iff repo does not exist yet. Otherwise pulls.
# Only works if repository path ends with '.git'
# Example: git_clone "git clone --branch 3.4.1 --depth=1 https://github.com/opencv/opencv.git"
