Honestly, I can't imagine redo all these modifications (357 files!) just to remove modifications related to trailing spaces :/

Here is an attempt to solve merge conflict. They are few things to fix which are not seen by merge conflict.

I think the CMake min version issue is resolved since min version is 3.10 in master branch. I've changed 3 more things: - hide all symbols by default => there...

Which compiler? I think it's fine with msvc, I'll try with a GNU compiler.

With apple-clang 13 on macOS, it works fine with `FCL_HIDE_ALL_SYMBOLS=ON`, `FCL_STATIC_LIBRARY=OFF` and `BUILD_TESTING=ON`. I use libccd v2.1 and eigen 3.4.0. While it compiles and links fine, when I run tests,...

I would say speed up compilation of downstream projects, by avoiding common template instantiations in fcl.

Ok so first thing to do to fix msvc shared with tests: turn `test_fcl_utility` to a static library. And I also see link errors of `test_fcl_collision` with Visual Studio, but...

Ok for Visual Studio, there were several missing declaration & definition of destructor, copy/move constructor/assignement in `Contact` & `ContactPoint` (though, it might be a bug in msvc). Moreover M_PI is...

For MinGW, there are indeed some link issues in tests (`test_collision_func_matrix` for me) with `ComputeBVImpl`. I'll see what I can do.
