# CMake
sudo apt-get install cmake

# google-glog + gflags
sudo apt-get install libgoogle-glog-dev

# BLAS & LAPACK
sudo apt-get install libatlas-base-dev

# Eigen3
sudo apt-get install libeigen3-dev

# SuiteSparse and CXSparse (optional)
# - If you want to build Ceres as a *static* library (the default)
# you can use the SuiteSparse package in the main Ubuntu package
# repository:
sudo apt-get install libsuitesparse-dev

# - However, if you want to build Ceres as a *shared* library, you must
# add the following PPA:
sudo add-apt-repository ppa:bzindovic/suitesparse-bugfix-1319687
sudo apt-get update
sudo apt-get install libsuitesparse-dev

# Optionally install Ceres, it can also be exported using CMake which
# allows Ceres to be used without requiring installation, see the documentation
# for the EXPORT_BUILD_DIR option for more information.
