I have succesfully made my first super simple proof-of-concept UGen and have now proceeded to turning some of my C++ code into UGens. For these more elaborate UGens, I am relying on a my own C++ library (https://github.com/Adampultz/pultzLib) that lives in my root folder and not in the SuperCollider source code.
I would like to point to the path of this library in my CMakeLists.txt, but not sure how.
I have tried:
set(EXTERNAL_LIBRARY_DIR ${CMAKE_CURRENT_SOURCE_DIR}/Users/adammac2023/Documents/GitHub/pultzLib)
and
include_directories(${EXTERNAL_LIBRARY_DIR})
but get the error
fatal error: 'Leaky_Integrator.h' file not found
I suspect there’s more to be added to CMakeLists.txt.
What am I missing?
My second question is, whether it is smarter to clone my library into the “external_libraries” folder in the first place? I did already try that, but it still doesn’t find the header filer.
Here’s my full CmakeLists.txt:
