Troubles while building

[Artholgar]

Hi there !

I was trying to build c-blosc following the installation guide and I've got some errors.
Note that I'm building it on windows, so I'm using minGW and MSYS.
My error occures at:

cmake --build .

and I've got this output:

Have you any clue to solve this ?
