CGAL users discussion list

[Andreas Fabri <>]

Hello,

In the CMakeList.txt file of the AABB_tree demo

you can see

____________
# Find CGAL and CGAL Qt4
find_package(CGAL COMPONENTS Qt4)
include( ${CGAL_USE_FILE} )
____________

This will try to find the CGAL lib you have just built

Some lines further down you can see:

____________
  # Link with CGAL
  target_link_libraries( AABB_demo ${CGAL_LIBRARIES} 
${CGAL_3RD_PARTY_LIBRARIES} )
____________

This will generate in the vcproj file or the Makefile
what is needed to link against the CGAL library


In the CMAkeList.txt of the examples the
target_link_libraries is part of a macro
to simplify things:

  create_single_source_cgal_program( "AABB_custom_example.cpp" )

Best,

andreas
