cisstNumerical Build Fails in Latest Release about cisst HOT 6 OPEN

There may also be an "external projects" option for building cisstNumerical within cisst. I'll leave it for @adeguet1 to answer.

I am using it with VS 2017, but I did not select the "Download Now" CMake option. I instead downloaded it separately (the source is also on GitHub/jhu-cisst) and built it from source using VS2017. Then, in cisst I used the CISSTNETLIB_USE_LOCAL_INSTALL CMake option.

Thanks @pkazanzides I was able to get it to work by building cisstNetLib myself.

We haven't implemented an "external project" way to build cisstNetlib. I'm not a big fan of CMake external projects so I tend to avoid them if a better "packaging" system exists (e.g. ROS/catkin) but I see the appeal for Mac OS or Windows. If I can implement the build using CMake external project, any objection to also remove the "download cisstNetlib now" option since it's a bit challenging to keep up with binary distributions.

No objection from me.

I have no objection to using CMake's external project. I've also had good success with CPM.cmake.

If you do go the external project route, would you still have the CISST_HAS_NETLIB option? I guess you would want CISST_USE_EXTERNAL and CISST_HAS_NETLIB to be enabled to build it this way?
