Hello,
I just came across that when you install CASToR with CMake, all the binaries are build in the build folder. However, when you install it with the provide Makefile, the binaries are in a bin folder.
In the documentation, sections 3.4.1 and 3.4.2, Installing CASToR with the provide Makefile (Item 4) and CMake (Item 6), to add CASToR to the environment, both methods say add
export PATH=$PATH:/path/to/CASToR/bin
to bash or zst. Maybe it needs a remark or note.
Best,
Seyyed
