// \brief Allows cmake to set up macro giving name of VXL source root directory

// Note: The make system (eg cmake) should generate a file, vcl_where_root_dir.h, from
// this, in which the macro is set correctly.
// For non-cmake systems this might cause a problem.  In particular if there is
// no vcl_where_root_dir.h, some other stuff might not compile.
// If we supply a default vcl_where_root_dir.h, it would be changed by cmake, and
// may get checked back into the repository by accident.

#define VCL_SOURCE_ROOT_DIR "${vxl_SOURCE_DIR}"
