[SofaKernel] FIX FileRepository on Windows

[guparan]

ADD dependencies to boost::filesystem and boost::locale

Fixes #17

[damienmarchal]

I cannot test myself on window but:
- the tests is not failing anymore.
- no new tests are failing.
- I don't think the new boost dependency is a problem.

I let @matthieu-nesme (who made the issue #17) to make the final decision.

[matthieu-nesme]

Great! and the fix is impressively concise.
The only concern could be the dynamic link to boost libraries, I guess it is mandatory?

[guparan]

Not all of them, we could replace ${Boost_LIBRARIES} with ${Boost_SYSTEM_LIBRARY} ${Boost_FILESYSTEM_LIBRARY} ${Boost_LOCALE_LIBRARY}

(edited)
No problem for me since boost is now mandatory.
As seen in the main CMakeLists.txt, line 158:
find_package(Boost REQUIRED)

Does the job, no test broken, fixes one failing test: green light for me.

Can I merge it ?

[guparan]

Nope, I have to search first for any header only improvement.

[guparan]

So there is no header-only way to use boost::filesystem and boost::locale.
The only improvement I see would be to move the find_package(Boost COMPONENTS filesystem locale QUIET) to SofaHelper.
Don't know if this would be a real improvement though 😕

[damienmarchal]

So we merge it this way ?

[guparan]

No objections so I vote yes :)
