PCL not finding QHull includes

I am using PCL and noticed that when I include pcl/surface/qhull.h there is an error while building:

 fatal error C1083: Cannot open include file: 'libqhull_r/libqhull_r.h': No such file or directory

The content of qhull.h is

#include <pcl/pcl_config.h>
#ifdef HAVE_QHULL

#if defined __GNUC__
#  pragma GCC system_header 
#endif

extern "C"
{
#include "libqhull_r/libqhull_r.h"
#include "libqhull_r/mem_r.h"
#include "libqhull_r/qset_r.h"
#include "libqhull_r/geom_r.h"
#include "libqhull_r/merge_r.h"
#include "libqhull_r/poly_r.h"
#include "libqhull_r/io_r.h"
#include "libqhull_r/stat_r.h"
}

#endif

So I don't get if HAVE_QHULL why can't it find the includes? How can I solve this?

Solution

  • In the end I had to reverse Engineer what PCL expects at CMake level from QHull by reading the dedicated CMake finding scripts. The problem is that the building environment I use is not doing this automatically such that I had to set the expected variables by myself.
