Support for Ninja broken in CMake 2.8.9

[Stefan Beller]

So running "cmake ." just works, i.e. the compiler is found correctly.
However when switching to Ninja instead of make, the compiler cannot be found.
See attached script output.

I figured out the problem.
There are 2 packages providing a ninja binary.

ninja - Privilege escalation detection system for GNU/Linux
ninja-build - small build system closest in spirit to Make

The priviledge escape detection system binary is located in /usr/sbin/ninja
while the build ninja is found in /usr/bin/ninja which has less priority in the PATH variable.

Uninstalling the Privilege escalation detection system helps.
After the uninstallation, and using a clean repository cmake works fine with ninja (the builder).

So there is a conflict when having installed both packages at the same time.

Hi, so based on your comment I'm closing this one.
