Summary0014337: CMAKE_FIND_ROOT_PATH is ignored in CMake 2.8.9, works for CMake 2.8.7
DescriptionI recently checked out my project on an Ubuntu 12.10 installation that has CMake 2.8.9. Until now I was working on a machine with older cmake version(CMake 2.8.7)

I have a toolchain file for cross compilation that sets CMAKE_FIND_ROOT_PATH variable. And I have several FindXXXX() in my scripts that search for installed libraries.

However when I run cmake(on the new machine) it complains that it cannot find the library(openal specifically). Adding a message(${CMAKE_FIND_ROOT_PATH}) at top of cmake-2.8/Modules/FindOpenAL.cmake reveals that CMAKE_FIND_ROOT_PATH has the correct value.

I downloaded the latest version(cmake-2.8.11.2-Linux-i386.tar.gz) and it has the same behavior.
I tried with cmake-2.8.7-Linux-i386.tar.gz and it worked. Exactly the same toolchain file, same CMakeLists.txt files, just different cmake binary.

I checked documentation and I didn't any major difference between CMake 2.8.7 and CMake 2.8.9.

I have the same issue with CMake 2.8.12.
Even "ONLY_CMAKE_FIND_ROOT_PATH" for find_path does not help.
But setting "PATHS ${CMAKE_FIND_ROOT_PATH}" and "NO_CMAKE_FIND_ROOT_PATH" works.

I got the same with CMake 3.3.1.

I compile with on Windows 7 using a Mingw32 compiler (i686-4.8.2-posix-dwarf-rt_v3-rev4).

Trying to find include fails. I needed to add path in the INCLUDE env variable to get it works.
