thanks for your report about this. However, to me, the lack of the --enable-R-
shlib option was not the only problem at this point:

Note that this error occurs in the R startup script itself. We try to query it 
for the value of R_HOME, but it bails out with an error on line 227, instead. 
This also means that you would not have been able to start a regular R session 
from the command line, either. Thus, it looks like your R installation was 
completely broken (for whatever reason).

Indeed, this is needed. If the above step had not failed, cmake would have 
proceeded to check for the existence of the shared library, shortly after, and 
would have given you a more helpful error message at that point.
