Hi, I am unable to install SCIP package 0.9.4 and receiving the following error.

I have already installed the SCIPoptsuite at this location C:\Program Files\SCIPOptSuite 7.0.1. However, while building SCIP, i am receiving the above-mentioned error. The package cannot locate the SCIP installation.

Can someone tell me how to resolve this issue? Apparently, it seems that SCIPOptSuite and SCIP package installations are at 2 different locations.
