1)strange error

You don’t need to add any variables.

Can you please describe your configure and build process step by step, with as much detail as possible? Thanks.

This can happen when the folder is not checked out from source (ie is not a git repository).

A workaround is to set that variable to something (1 is fine) and also set the SlicerHeart\_WC\_REVISION to 1 as well. This will bypass the version control checks.

Edit: if it’s a sub project, you’ll have to add the \<projectname\>\_WC\_REVISION variable to the project failing to configure.

The successfully compiled SlicerHeart has been installled mannully , by adding the directory Edit-\>Setting-\>Module. Some function need the SlicerIGT module installed first, this module is added the same as SlicerHeart. But when calling the SlicerHeart, Slicer GUI shows a error message-box, SlicerHeart haven’t installed… how to solve this kind of question? thansk

You need to add the SlicerIGT build folders to the additional module paths, too:  
`...\SlicerIGT_R\lib\Slicer-4.13\qt-loadable-modules\Release`  
`...\SlicerIGT_R\lib\Slicer-4.13\qt-scripted-modules`

After exactly added the …/Release directory（firstly just to the …-modules directory）, all problem solved. Perfect!  
Thanks!
