KDevelop can't load project: "too large document"?

[Matthew Woehlke]

I'm trying to load my KDevelop project created for
https://github.com/kitware/kwiver. However, KDevelop says that it is
"loading project", but never finishes. When I dump KDevelop's stack
(pstack), all of the threads seem to be waiting (in poll or
pthread_cond_wait).

When I run latest master, I get:

    kdevelop.plugins.cmake: error processing "too large document"

...followed by 100 MiB of JSON that appears to be the output of CMake
parsing the project.

Any thoughts? I'd *really* like to be able to open this project!
