Build failure, missing JSON.h?

Using latest esp-idf master and ESP32_Explorer as of today.

$ make

@chmorgan You need to add this library to components (whole cpp_utils): https://github.com/nkolban/esp32-snippets/tree/master/cpp_utils

[chmorgan]

Not using a submodule to pull that in?

[chegewara]

No, its just symlink from our dev environment. You need to do this manually by copying folder or with symlink.

[chmorgan]

Ahh. Submodule would make that automatic for users :-)

I'll pull it in and try rebuilding, thanks for the pointer.

[chmorgan]

Things are building now.

I'm trying to see how much space nghttp2 is taking up but I'm having trouble seeing it apart from the rest of the code. It looks like it isn't built in as a component. I'm trying to do a size comparison of nghttp2 vs. libesphttpd to see if I should switch http servers.
