# This file should be used as a template for creating new projects with Python
# wrapping using the CMake tools

# * 1. To create your own project, replace "gtsam_example" with the actual name
#   of your project
cmake_minimum_required(VERSION 3.9)

# * 2. Find GTSAM components so we have access to the GTSAM Cython install path
find_package(GTSAM REQUIRED) # Uses installed package
# Note: Since Jan-2019, GTSAMConfig.cmake defines exported CMake targets that
# automatically do include the include_directories() without the need to call
# include_directories(), just target_link_libraries(NAME gtsam)
# include_directories(${GTSAM_INCLUDE_DIR})

# * 3. Add the local source directory for CMake Ensure that local folder is
#   searched before library folders
include_directories(BEFORE "${PROJECT_SOURCE_DIR}")

# ##############################################################################
# * 4. Build static library from common sources. This is a common cmake step
#   where we load all the source files and link against the GTSAM library.
