Graphviz: Fix issue with too many open file streams on Windows platform (!5088) · Merge requests · CMake / CMake

Stephan Rohmen requested to merge srohmen/cmake:FixTooManyOpenFiles into master Jul 31, 2020

The per-target graphviz dependency generation was limited by the concurrently open file streams possible on Windows. With this fix, CMake opens one file stream after another, writes the data and closes the stream when finished.

Fixes #20931 (closed)
