spdlog/sinks/callback_sink.h: No such file or directory

I am trying to integrate the spdlog into my project. However I get the below error when I run the example code. ` build$ cmake ../ -- The CXX compiler identification is GNU 9.4.0 -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Looking for C++ include pthread.h -- Looking for C++ include pthread.h - found -- Performing Test CMAKE_HAVE_LIBC_PTHREAD -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE

The operating system is Ubuntu 20.04. Run sudo apt install libspdlog-dev to install the package.

If you have sudo apt install libspdlog-dev to install spdlog on your machine, you do not need to build spdlog. Since it is specified as a dependency of libspdlog-dev, libspdlog1 should also be installed.

And since the commit 3cab260814613b0a7e6889d2a030b2992c916d1a with the callback_sink added has not yet been released, you are trying to build a different source code than libspdlog-dev. The project incorporates the latest spdlog source code, but the included header files appear to refer to the source code installed on the machine by libspdlog-dev.

I can only assume that there is a problem with your project.
