compile error eigen -> eigen3 and No matching fct nanoflann::KDTreeSingleIndexAdaptorParams

[busybeaver42]

First error:
bugfix in type.h and FRICP.h change entry:
#include <eigen/...> to #include <eigen3/...>

second error:
Fast-Robust-ICP/ICP.h:44:57: error: no matching function for call to ‘nanoflann::KDTreeSingleIndexAdaptorParams::KDTreeSingleIndexAdaptorParams(const int&, const size_t&)’
index = new index_t(dims, *this, nanoflann::KDTreeSingleIndexAdaptorParams(leaf_max_size, dims));
solution is open, ...

No support here, but I found a solution:

First install nanoflann:
https://github.com/jlblancoc/nanoflann

fix in type.h and FRICP.h
#include <eigen/...> to #include <eigen3/...>
Fix in ICP.h line 44:
//index = new index_t(dims, *this, nanoflann::KDTreeSingleIndexAdaptorParams(leaf_max_size, dims));
index = new index_t(dims, *this, nanoflann::KDTreeSingleIndexAdaptorParams(leaf_max_size));

It seems that in include/ directory, there exists a file called nanoflann.hpp, but maybe the author didnot add the path to the makefile.

Solution:

1. Edit makefile 'CMakeLists.txt' and remove any system NanoFlann-library (comment out):
   #--- Nanoflann
   #find_package(NanoFlann REQUIRED)
   #include_directories(${NANOFLANN_INCLUDE_DIR})

2. Edit 'ICP.h' and change to project-included NanoFlann:
   #include "include/nanoflann.hpp"
