CMakeLists: create data, or symlink data?

https://github.com/sandialabs/InterSpec/blame/master/CMakeLists.txt#L1184

This line creates the "data" folder in the build directory.

At: https://github.com/sandialabs/InterSpec/blame/master/CMakeLists.txt#L1217

The CMakeLists attempt to create a symlink to the data directory in the source code.

This creates a conflict, since the data directory already exists at the time when a data symlink is supposed to be created.

One resolution would be to move line 1184 down after the symlink is created.

This hadn't triggered for me, but is clearly and issue - thanks for the for the suggested fix!
