#2842: Silo captures incorrect LIBS values on second CST run

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

In git hash [49ef0de](https://github.com/EinsteinToolkit/ExternalLibraries-Silo/commits/49ef0de20f...) "Silo: capture option list LIBS and LIBDIRS" of [ExternalLibraries-Silo](https://github.com/EinsteinToolkit/ExternalLibraries-Silo) code was added to capture LIBS for systems where extra libraries are required to make simple code compile. This introduced a different sort of bug.

It only captures the correct `LIBS` once when CST for PETSc runs in a "clean" configuration. Afterwards `LIBS` is set to the full set of ExternalLibraries in the makefile before CST runs and thus it captures all libraries.

A correct fix would seem to require changes to the flesh [720ef037](https://bitbucket.org/cactuscode/cactus/commits/720ef0372df4089a51e777fd8ad7...) "Cactus: keep track of ExternalLibs separately from Libs" of [cactus](https://bitbucket.org/cactuscode/cactus)

Related to #2821 which has the same issue with LIBS.
