Jansson compilation issue

[avkplus]

Hi friends!
I can't compile Jannson library.
I tried different systems, different compilers, but the library does not compile.
I followed all the steps to install the library according to the instructions.

System 1:
Linux kunhab 6.1.50-current-rockchip64 #3 SMP PREEMPT Wed Aug 30 14:11:13 UTC 2023 aarch64 GNU/Linux

System 2:
Linux fx-ThinkPad-E14 5.4.0-65-generic #73~18.04.1-Ubuntu SMP Tue Jan 19 09:02:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

My installation steps:
git clone https://github.com/neugates/jansson.git
cd jansson && mkdir build && cd build
cmake -DJANSSON_BUILD_DOCS=OFF -DJANSSON_EXAMPLES=OFF ..
make
make check

	Errors while running CTest

sudo make install

-- Installing: /usr/local/lib/cmake/jansson/janssonTargets-noconfig.cmake

The libraries libjansson.so don't compiling.
The same error occurs on both systems.
I think the version libjansson on GitHub is broken.
Please tell me what I can do to compile the library?
