Dependency Management

• header only library: e.g. glm, fmt, catch2, etc.
• simple cmake-built library, e.g. partio
• complex cmake-built library, e.g. openvdb
  • use a C++ package manager
  • still deciding among these choices: conan, vcpkg, build2, hunter
  • currently using conan due to its proper balance between flexibility and simplicity
• non cmake-built library
  • write a customized FindPkg.cmake file to search for associated header files and libraries in certain paths
