Single-Config Ninja build fails on Windows April 2022

[traversaro]

I tried to build locally with ninja, and it is failing with error:

-- Long integers (64bit) are ON
-- Configuring done
-- Generating done
CMake Error:
  Running

   'C:/Users/STraversaro/AppData/Local/mambaforge/envs/robsub/Library/bin/ninja.exe' '-C' 'C:/src/robotology-superbuild/build/src/osqp' '-t' 'recompact'

  failed with:

   ninja: error: build.ninja:320: multiple rules generate out/osqp.lib [-w dupbuild=err]





CMake Generate step failed.  Build files cannot be regenerated correctly.
ninja: build stopped: subcommand failed.

Probably related to tesseract-robotics/trajopt#287 .

Apparently Windows-rebuild of the superbuild takes a lot of time. Ideally solving this and conda-forge/vc-feedstock#39 and documenting the ninja based workflow could drastically improve this.

Today I did for debug a build with ROBOTOLOGY_ENABLE_DYNAMICS_FULL_DEPS and I took literally forever, I think it is quite important to fix this.
