Some more info:
In Insight/Wrapping/WrapITKConfig.cmake.in we have:
IF("${WrapITK_DIR}" MATCHES "^${CMAKE_INSTALL_PREFIX}")
STRING(REGEX REPLACE "^${CMAKE_INSTALL_PREFIX}/*" "" prefix "${WrapITK_DIR}")
SET(WRAP_ITK_INSTALL_PREFIX "${prefix}" CACHE PATH "subpath where
where most of WrapITK files will be installed")
ELSE("${WrapITK_DIR}" MATCHES "^${CMAKE_INSTALL_PREFIX}")
MESSAGE("Warning: the CMAKE_INSTALL_PREFIX doesn't match the WrapITK
one. Your installation may not be usable.")
SET(WRAP_ITK_INSTALL_PREFIX "@WRAP_ITK_INSTALL_PREFIX@" CACHE PATH
"subpath where where most of WrapITK files will be installed")
ENDIF("${WrapITK_DIR}" MATCHES "^${CMAKE_INSTALL_PREFIX}")
That second clause seems to be causing the problem, because in
Insight-build/Wrapping/WrapITKConfig.cmake it becomes:
ELSE("${WrapITK_DIR}" MATCHES "^${CMAKE_INSTALL_PREFIX}")
MESSAGE("Warning: the CMAKE_INSTALL_PREFIX doesn't match the WrapITK
one. Your installation may not be usable.")
SET(WRAP_ITK_INSTALL_PREFIX
"lib/cmake/ITK-4.0/WrapITK/;CACHE;INTERNAL;PATH;subpath where where
most of WrapITK files will be installed" CACHE PATH "subpath where
where most of WrapITK files will be installed")
ENDIF("${WrapITK_DIR}" MATCHES "^${CMAKE_INSTALL_PREFIX}")
(note the concatenation of keywords into one long value string)
I'm building the whole thing as per the instructions on
http://www.vtk.org/Wiki/ITK/Release_4/Wrapping/WrapITK_Installation --
this means that CMAKE_INSTALL_PREFIX is the ITK install prefix, and
that WrapITK_DIR by definition has to be that +Wrapping, which means
I'll always strike the second clause in the conditional above. I hope
that I'm missing something here.
Any tips would be much appreciated!
