Hmm.  See if you can reproduce it with something simple like:

 $ cat test.cmake
 find_program(MATLAB NAMES matlab)
 message(MATLAB=${MATLAB})
 $ cmake -P test.cmake

Then build your own CMake with -DCMAKE_BUILD_TYPE=Debug and run it in
a debugger to track down what goes wrong.  Set a breakpoint on
"cmsys::SystemTools::FileExists" to step through the low level checks.

I meant that when checking for existence and permissions it uses
something equivalent to "stat" as against "lstat".  A broken symlink
is not considered to exist.  It certainly doesn't resolve symlinks
in the returned path.
