Re: [Discuss-gnuradio] OOT adding c++ library

[Martin Braun]

Santos,

this depends on a lot of things. Here's an example:
https://github.com/stwunsch/gr-nacl/blob/d6dd3c02dcda3f601979908b61b1595476f6bf95/CMakeLists.txt#L144-L152

gr-nacl uses libsodium as an external dependency. You can see all the
variables that contain SODIUM; they are in fact generated by this line:

https://github.com/stwunsch/gr-nacl/blob/d6dd3c02dcda3f601979908b61b1595476f6bf95/CMakeLists.txt#L111

...typically, that's a workflow you want. If your dependency doesn't
have a way to be picked up by CMake, you can point to the library files
directly.
