[cmake-developers] slow regex implementation in RegularExpression

[David Cole]

The "setenv" output will be gone (by default) as of CMake 2.8.7
because of this recent commit:

  http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=5a94d099ddbd8f3d4b850957faa8c11f619c6f18

Does using ctest from 'next' or 'master' already show any improvement
over 2.8.6?
