fixes for Master 27 under Linux

[wschadow]

The fixes (typos, paths to include files, type corrections) make it possible to compile and run under Linux. In additon I've added profiles and .mo files.

With the last changes it is possible to build the code under Linux (tested Debian Buster), Win (tested 10), and macOS (tested Catalina 10.14) now. The Slicer is working in "general", but has not been tested in depth.

Thanks

I edited a new commit, as many elements shouldn't be added (like profiles)
I also changed the #include "../XX" by #include "libslic3r/XXX, as it's safer if the file move again.
I reuse your macos build file, and updated the linux one to include -wrt

little notes:

• "CMP0135" is set two times in deps/cmakefiles
• sla/concurency is deleted, and sla/indexedmesh is now renamed AABBmesh

questions:
why revert libtiff to 4.1 for apple?

[wschadow]

Thanks for you notes.

Using libtiff 4.6 under masOS does not work. It cannot find CMATH::cmath in that case.

right.
Prusa remove libtiff in 2.8, so i'll try by removing it rn.

[wschadow]

yes, there was a parameter missing as well. Prusa commented on my pull request #12382
that libtiff will be be removed. I think it is not explicitly used and just a compile option for wxwidgets. It may be removed easily.

[wschadow]

yes, it's easy to remove 49e646d5c1ef6c1b854a87ab6e559b055a8d24ac
