link to cgal

Sorry to bother you .

I try again with VS2019 built in cmake, rather than cmake standalone. I edit the Cmakesettings.json as follows:

{
"configurations": [
{
"name": "x64-Release",
"generator": "Ninja",
"configurationType": "RelWithDebInfo",
"inheritEnvironments": [ "msvc_x64_x64" ],
"buildRoot": "E:/OpenGR/build",
"installRoot": "E:/OpenGR/build/install",
"cmakeCommandArgs": "",
"buildCommandArgs": "-v",
"ctestCommandArgs": "",
"variables": []
}
]
}

It compiles and installed successfully. In E:/OpenGR/build/install , I got these folders: -assets-bin-doc-include-lib-scripts.

I run the /scripts/run-example and it runs successfully. But when I run /bin/Super4PCS.exe with two hippo.obj, the result is

PS E:\OpenGR\build\install\bin> ./Super4PCS -i ../assets/hippo1.obj ../assets/hippo2.obj -o 0.3 -n 500

0 0 0 1
Exporting Registered geometry to output.obj...
Export DONE

It seems not work.

=====================
And I have another question about how to link OpenGr to CGAL.

Now I got three OpenGRConfig.cmake files, which are
E:\OpenGR\build\OpenGRConfig.cmake,
E:\OpenGR\build\generated\OpenGRConfig.cmake
E:\OpenGR\build\install\lib\cmake\opengr\OpenGRConfig.cmake

So which one should I link to OpenGR_DIR(at cmake-gui) when compile CGAL-5.1.2\examples\Point_set_processing_3?

I tried all of them. Two of them can compile successfully. But when I open the project: registration_with_OpenGR in VS2019 and build it. It says

Error: cannot read file E:/CGAL-5.1.2-examples/CGAL-5.1.2/examples/Point_set_processing_3/data/hippo1.ply

While other projects which dont need OpenGR can run well.

It is an issue about CGAL demos. Now everything works well. Thanks.
