matplotlib: only use pkgconf if it's a dependency (!376) · Merge requests · ParaView / common-superbuild

Ben Boeckel requested to merge ben.boeckel/common-superbuild:matplotlib-pkgconf-depends into master Nov 20, 2020

We assume pkg-config is provided by the host on Linux. We should only set the PKG_CONFIG environment variable if the dependency is actually available.

Reported and debugged here: https://discourse.paraview.org/t/paraview-5-9-0-rc1-superbuild-package-configuration-issue-affecting-matplotlibs-detection-of-freetype-and-zlib/5831
