[Rcpp-devel] Rcpp, Windows and CMake

[Jamie Olson]

Thanks!

The WIN.readme.txt instructs you to run

cmake -G "Unix Makefiles" ..

It seems that the only cmake on windows that supports "Unix Makefiles"
is the cygwin version, and from what you've said it sounds like that
can't be used with the native MinGW required for Rcpp.
