Use proxsuite when using the superbuild

[xEnVrE]

We need to use proxsuite for a project involving robots for which we also use the robotology-superbuild. Given that we were not aware of the fact that the superbuild fetches and installs that library, we have cloned proxsuite and installed on the system..

We then realized that something was wrong as our CMake project could not find the proxsuite::proxsuite-vectorized target. After some investigation we discovered that our project was indeed try to link against the proxsuite library installed by the superbuild which however is compiled with -DBUILD_WITH_VECTORIZATION_SUPPORT:BOOL=OFF to support Ubuntu 20.04.

Could you give us a suggestion for this scenario? At the moment we are forcing CMake to use our installation, built with vectorization, by exporting proxsuite_DIR.

Thanks

Can we have a quick chat today to understand the context on this? Thanks! @xEnVrE @PasMarra
