TST tools with vasp 6.2.1

[Neutrino]

Dear All,

I'm trying to install the most recent version of TST tools with VASP 6.2.1. At the step:
"To build the code, the VASP makefile needs to be changed. Find the variable SOURCE, which defines which objects will be built, and add the following objects before chain.o"

I'm unable to locate the variable SOURCE at all to insert the needed modification. Any hint is highly appreciated.

Look in the src/.objects file.

Thank you so much!
