Hi,

you say youve edited the CMakeCache.txt to set it to the correct 
directory... but your working directory is /tmp_mnt/singularity/...
yet you have set the directory as just /singularity/...

if you get the same errors after changing 
CMAKE_CACHEFILE_DIR:INTERNAL=/singularity/maxa/home/galen/src/vtk/VTK
to
CMAKE_CACHEFILE_DIR:INTERNAL=/tmp_mnt/singularity/maxa/home/galen/src/vtk/VTK

then CMake is probably rewriting your CMakeCache.txt when it shouldnt.

>From my rather vague memory there is a "c" command in CMake which configures 
things, probably altering values in CMakeCache.txt -- and it has a "g" 
for generate-- to generate the makefiles for VTK. After you have edited 
the directory directly in the CMakeCache.txt file you probably just need to 
do "g", not "c".

If just using "g" doesnt work, try editing the file to fix the incorrect 
directory and then make the file read-only so CMake can't rewrite it.

Good luck!

BTW i think VTK should dump CMake. It seems to have problems on MacOS X,
and its just an annoying nuisance overall. There must be better tools out 
there.

Also, some more informative help strings on each of the VTK options you can 
set in CMake would make building VTK easier...
