opae_FOUND to FALSE when install opae-sim

[DatNguyen97-VN]

Dear Admin,

I want to install opae-sim to use afu_json_mgr and afu_sim_setup command.

Setup Info

Ubuntu 24.04 on WSL2

Action

git clone https://github.com/OPAE/opae-sim.git
cd opae-sim
mkdir build
opae_DIR=/usr/local/lib/opae-2.14.0 cmake ..

Result

  but it set opae_FOUND to FALSE so package "opae" is considered to be NOT
  FOUND.  Reason given by package:

  The following imported targets are referenced, but are missing:
  json-c::json-c

Please help me to fix this error.
Thank you,

json-c is an external package that you must install. I’m not sure what it is called on Ubuntu but it is almost certainly available as a standard package. You might need the development version.

Hi @michael-adler, i installed json-c with 0.16 version

ppkg-config --modversion json-c
0.16

ls /usr/local/include/json-c/

arraylist.h  json.h            json_config.h    json_object.h           json_pointer.h  json_types.h  json_visit.h  printbuf.h
debug.h      json_c_version.h  json_inttypes.h  json_object_iterator.h  json_tokener.h  json_util.h   linkhash.h

But it is still error:
