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.
