Issue with rapidjson when building about vrs

[jmpfar]

Alright, I wasn't aware that cmake is supposed to import a library's CMakeLists.txt in find_package but I only recently started working with it so that makes perfect sense. If that's the case then this sounds like this is an issue in my specific environment

Feel free to close, in any case it might be helpful to anyone seeing the same error

EXTERNAL_DEPENDENCIES_DIR should always end up being set by this code , which is at the top of the cmake code. I'm not sure how it's not set for you, but you need to make sure to include that top cmake file, that's a requirement. The other cmake lists should not be accessed directly.

Hey, thanks for the reply!
So my flow was as mentioned here:

I compiled and installed the library locally, I then added find_package(vrslib REQUIRED) to my cmake file. That line failed with the above mentioned error. So reading your response, do you think I should have imported that CMakeLists.txt file manually because for some reason it wasn't included on its own?

The code I pointed to sets EXTERNAL_DEPENDENCIES_DIR if it's not set externally, which is an optional customization option given to the users of the library. You need to debug why it's not happening for you, because you should not get to the FindRapidjsonLib.cmake file without going through that code first.
I'm not sure I understand your question. The only CMakeLists.txt in the vrs project you should use directly is the top one, in the main folder.
