CMP0075 warning with CMake 3.12 and HDF5 1.10

HDF5 Library
1

We have HDF5 (snapshot from branch 1.10) embedded into ITK.

Recently, CMake 3.12 was released. If that version is used to configure ITK, a warning is displayed (complete message below). I have created a patch to get rid of the warning. But I don’t know how to contribute this to HDF5? Can someone point me to documentation of how to create a pull request or something similar? Or just apply this patch to hdf5_1_10 branch? I think that develop might want a different solution from just disabling the warning.

The slightly updated patch has been merged into ITK master branch.

Thank you for the patch!

Please send it to help@hdfgroup.org and we will review it.

All,

We are working on opening our Git repository (Bitbucket) to the community. Unfortunately, it is taking a little bit longer than we anticipated, but we will get there. Thank you for your patience.
