ENH: provide separate makeSCOTCH script for independent use
- improve handling of scotch build toolchain - relax the test for existence of libscotcherrexit, which can also be incorporated into libscotch itself
I just followed the code development guidelines and found that the Allwmake script fails because it cannot find the folder ThirdParty-plus/scotch_6.0.6.
Downloading scotch from their webpage obviously solves this, but maybe it would be a good idea to let the compilation of OpenFOAM continue eventhough scotch is not present in ThirdParty. Or is it maybe not possible to compile OpenFOAM without scotch? In so, it would be very convenient, if the Allwmake script took care of the downloading. Or maybe just an error message telling the user where to download scotch.
Just a suggestion.
