My first subject line was "Who decided to break FindITK.cmake in
2.8.4?" but that isn't probably very tactful.
We have a whole bunch of projects that used to configure and build
just fine with CMake 2.8.3. With 2.8.4 they fail.
The error message we get is:
CMake Error at /opt/cmake-2.8.4-Darwin-universal/CMake
2.8-4.app/Contents/share/cmake-2.8/Modules/FindITK.cmake:52 (MESSAGE):
Please set ITK_DIR to the directory containing ITKConfig.cmake. This is
either the root of the build tree, or PREFIX/lib/InsightToolkit for an
installation.
Call Stack (most recent call first):
BuildScripts/CMakeCommonExternalDefinitions.cmake:23 (find_package)
CMakeLists.txt:70 (PACKAGE_NEEDS_ITK)
We DO set ITK_DIR at configure time, and I HAVE verified that
ITKConfig.cmake DOES exist in ${ITK_DIR}.
Looking at the difference between FindITK.cmake in 2.8.3 and 2.8.4 it
looks like someone replaced trusting the ITK_DIR variable and using it
directly if defined, with
FIND_PACKAGE(ITK QUIET NO_MODULE
NAMES ITK InsightToolkit CONFIGS ITKConfig.cmake)
Which doesn't work -- it appears to ignore ITK_DIR and doggedly insist
that it can't find ITK.
What gives?
