CMake can be told to build the separate Stanford modules in
stdproc via the ISCE2_WITH_STANFORD configuration option.
If not specified, it will be auto-enabled at configuration time if the
stanford_license magic is not None.
This commit adds experimental CMake build support for ISCE2.
The only changes involved should be adding CMakeLists.txt files.
All current source files, headers, and other functionality, including
the existing SCons build system, should be unaffected.
Some functionality is still a work-in-progress.
These should all be marked as TODO in the CMakeLists.txt files.
`grep TODO **.txt`
Please read CMakeLists.txt and .cmake/*.cmake for more info.
