Fix not working ninja multi config on coin

On coin we call cmake --build . and we do not specify
the config expecting that all configuration are build.
However, when using the custom command for ninja build
dependencies are incorrectly resolved by cmake and
the ninja step is only executed in "default" config context.
This breaks debug builds. Cmake 3.20 fixes the issue
by adding genex to OUTPUT and support for OUTPUT_CONFIG.

Create workaround for now and revert it when minimum version
of cmake is bumped to 3.20
