One thing that may help is this (somewhat older, but I believe still
accurate) post from Riccardo:
https://sourceforge.net/p/rdkit/mailman/message/30074971/
It's been a while since I looked at this (since I mainly use conda these
days), but I just did a quick experiment with:
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/rdkit_test -DRDK_INSTALL_INTREE=OFF ..
followed by
make install
and that seems to have worked.
This type of install behaves somewhat differently from what the
documentation describes. It arranges the files in the PREFIX directory like
"normal" software is arranged. So as a user I need to set my PYTHONPATH
like this:
export PYTHONPATH=/opt/rdkit_test/lib/python3.5/site-packages
and modify LD_LIBRARY_PATH to include: /opt/rdkit_test/lib
RDBASE is:
export RDBASE=/opt/rdkit_test/share/RDKit
This is not documented in any useful way, which is something that we ought
to change.
