libminc and/or ITK not accessible in minc4itk build when building with system ITK

Building in a clean sandbox:

           Volume grid=static_cast<Volume>(xfm->displacement_volume);
           ^

followed by lots of resulting syntax (!) errors.

Flags:

  -DCMAKE_INSTALL_PREFIX=$out
  -DMT_BUILD_SHARED_LIBS=ON
  -DUSE_SYSTEM_FFTW3F=ON
  -DUSE_SYSTEM_GSL=ON
  -DUSE_SYSTEM_HDF5=ON
  -DUSE_SYSTEM_ITK=ON
  -DUSE_SYSTEM_NETCDF=ON
  -DUSE_SYSTEM_PCRE=ON
  -DUSE_SYSTEM_ZLIB=ON
  -DMT_BUILD_VISUAL_TOOLS=ON
  -DMT_BUILD_ITK_TOOLS=ON
  -DMT_BUILD_MINC_ANTS=ON

but this happens with/without shared libs and with/without superbuild (e.g., not using system (say) fftw3f; see next-most-recent bug). ITK version is 4.0.0.

If I turn off BUILD_ITK_TOOLS, the build succeeds.

Oh, I assume I wasn't supposed to use ITK4 - closing for now.

Using an existing ITK 3 doesn't seem to work either:

CMake Warning at CMakeLists.txt:319 (FIND_PACKAGE):
  By not providing "FindITK.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "ITK", but
  CMake did not find one.

  Could not find a package configuration file provided by "ITK" with any of
  the following names:

    ITKConfig.cmake
    itk-config.cmake

  Add the installation prefix of "ITK" to CMAKE_PREFIX_PATH or set "ITK_DIR"
  to a directory containing one of the above files.  If "ITK" provides a
  separate development package or SDK, be sure it has been installed.
