[gmx-developers] couple of cmake questions/problems

[Szilárd Páll]

Hi,

> available in cmake 2.8. Do we require 2.8 or 2.6?

unset was introduced in 2.6.3. RC 10
(http://www.cmake.org/files/v2.6/CMakeChangeLog-2.6.4), that's why
when GMX_OPENMM=ON the required version is 2.6.4.

I didn't know about FindMPI also using unset though. We might want to
bump the required version to 2.6.4 for the entire project. We didn't
do this before as some OS-es (like Debian and CentOS) have only
<v2.6.4 in the repositories.

Cheers,
