I am trying to install and run the application but I am unable to because oatpp-swagger isn't found.

Which is caused because the cmake for oatpp-swagger module is failing.

CMake Error at CMakeLists.txt:103 (add_compile_definitions):
 Unknown CMake command "add_compile_definitions".

Opened /bin/ash from the container to find the cmake version to be 3.11.1.

cmake version 3.11.1

According to this the cmake version needs to be >=3.12 to use "add_compile_definitions"

The docker image needs to be upgraded with a higher version of cmake. That should solve this issue.
