bug#32691: OpenMolcas

[Ludovic Courtès]

Hi Eric,

We’re almost there!  :-)

I made small changes (moved comments about the patch at the top of the
patch; switch to ‘texlive-union’, which is much smaller than ‘texlive’),
leading to the attached patch.

It’s all good, except that the file layout really doesn’t match the
usual conventions:

Ideally basis_library/ and data/ would go under share/openmolcas, while
CONTRIBUTORS.md and LICENSE would go to share/doc/openmolcas.  Also, it
would be nice to remove the ‘.exe’ extension.

Do you think you could easily fiddle with CMake to fix these and/or
report it upstream?  I could apply the patch as is but I think users may
not be pleased by this.  WDYT?

Thank you for your time, and sorry for the extra round trip!

Ludo’.

+By default, pymolcas is installed in the first writable directory in the

+OpenMolcas binaries.
