@traversaro, thanks for the PR!

Thanks for the comment @PhoebeHui ! I fixed all the problems, and now the port should work fine, I am not sure what happened to the CI jobs that staled.

Is the author of the library using it? if not, we should not add this in vcpkg. See https://github.com/microsoft/vcpkg/blob/master/docs/maintainers/maintainer-guide.md#do-not-add-cmake_windows_export_all_symbols

tiny-process-library is a small library with a few function and no templates, so CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS works as intended. It was already used in the patch that this PR removes. Furthermore, it was also added upstream in https://gitlab.com/eidheim/tiny-process-library/-/merge_requests/39, but it is set for an error after the add_library call, so it does not work as intended. Passing it for a command line is just a way to solve this problem before it is solved upstream (like a patch, but more future-proof).

@strega-nil, could you help confirm?

[strega-nil]

Yeah, LGTM

fyi @j-rivero, if you want to include tiny-process-library in the Gazebo vcpkg dependencies for compiling the Gazebo main command on Windows, after this PR the version that exports the correct CMake imported target is available in vpckg.

And thanks a lot @PhoebeHui and @strega-nil for reviewing and merging this!

Thanks Silvio. Gazebo classic is not using dependencies from vcpkg in our CI, something I will need to fix or change at some point.
