Compiling mergerfs

For Developers
1

Hello,

EDIT: Back to square one

I'm trying to compile mergerfs based on Makefile here https://forum.turris.cz/t/cross-compile-howto/1090/18 now using SDK 23.05.0-rc2 and older mergerfs 2.21 source.

Now it's failing to find fuse.h which is strange because I can find this in included dir, I wonder why?

Thanks for any advice.

make package/mergerfs/compile
