Andrew, Thanks for letting me know. Let me know if you have any more issues.
Ben: at some point I was the maintainer for FindMPI. Are you the official maintainer now? Do you want to be? I have very limited ability to test on Windows, and that seems to be where most of the problems are. -Todd From: Andrew Maclean <andrew.amacl...@gmail.com> Reply-To: "andrew.amacl...@gmail.com" <andrew.amacl...@gmail.com> Date: Sunday, March 1, 2015 at 11:31 PM To: Todd Gamblin <tgamb...@llnl.gov>, "cmake@cmake.org" <cmake@cmake.org>, Ben Boeckel <ben.boec...@kitware.com> Subject: Re: FindMPI.cmake and MS-MPI > Please ignore my emails regarding this.
