find_program: Restore leading double slash on Windows network path (!3105) · Merge requests · CMake / CMake

Brad King requested to merge brad.king/cmake:find_program-windows-share into master Mar 14, 2019

Since !2120 (merged) we accidentally convert the leading // to just / on results with Windows network paths.

This was caused by CollapseCombinedPath being less robust than CollapseFullPath. Restore use of the latter but in a way that preserves the requirement of the above commit to support candidates that are themselves absolute.

Fixes: #19049 (closed)
