Windows CI fails on header self-containment if the generated program name is too long

[mrlag31]

Having a header two folders down from src makes the Windows CI fail with the following error (taken from #950):

LINK : fatal error LNK1104: cannot open file 'D:\a\ArborX\ArborX\build\test\headers_self_contained\Debug\ArborX_HeaderSelfContained_interpolation_details_ArborX_InterpDetailsSymmetricPseudoInverseSVD_hpp.exe' [D:\a\ArborX\ArborX\build\test\headers_self_contained\ArborX_HeaderSelfContained_interpolation_details_ArborX_InterpDetailsSymmetricPseudoInverseSVD_hpp.vcxproj]

This issue does not appear if the file is only a folder down from src.

After more experiments, it seems to be because the generated filename is too long for the linker, and it has nothing to do with the folders. Shorter file / folder names work perfectly.

It could be running into 256 character limitations of Windows file system.
