#2875: handle system directories when looking for (extra) hdf5 libraries

Reporter: Roland Haas Status: resolved Milestone: ET_2025_05 Version: Type: bug Priority: major Component: EinsteinToolkit thorn

Comment (by Roland Haas):

The `--keep-system-libs` option is only known starting pkg-confg version 0.7 (from 2012) and at least Ubuntu 20.04 uses an older version (0.29). To avoid this issue I have updated the commit to use the environment variable `PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1` which has the same effect on new enough `pkg-config` and is silently ignored by older ones.
