C++ 17 and boost filesystem

[sloriot]

Hi,

I see in some CMakeLists that you require c++17. If that's the case, would you accept a PR that replaces boost filesystem with the filesystem of the STL?

Hello @sloriot and thanks for the offer!
We already replaced boost::filesystem in the develop branch, see this PR: #581. There were some instabilities on our build server so it hasn't been merged to master yet. I believe they were fixed, so you can expect a new release of libpointmatcher later this week.

Oh that's great, Thanks! I'll close the issue.

PS: I did try the develop branch @f42ea4ba7525646a9f2a2d723d341a2515fc6084 and it seems that something changed in the cmake magic. AFAIR, I could use it directly from the build dir but ${libpointmatcher_INCLUDE_DIRS} only contains eigen path and not libpointmatcher include path. Trying make install does not help as it complains that it can't find libpointmatcher-config.cmake (wasn't copied most probably).
