Comilation fails on MSys64

[velteyn]

Hello, my attempt to compile the project in MSYS64 was unsuccessful

I installed all the dependencies but I obtain this:

I forgot to write another interesting clue:

*** Warning: Trying to link with static lib archive /usr/lib/libjansson.a.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because the file extensions .a of this argument makes me believe
*** that it is just a static archive that I should not use here.

I can I have the shared library ?
When I do:
$ ls /usr/lib/libja*
I obtain :
/usr/lib/libjansson.a /usr/lib/libjansson.dll.a /usr/lib/libjansson.la
