non standard name of a dependency

[Catonano]

I don't know if this is the right place to ask. If it's not, I apologize

I'd like to build guile-commonmark (
https://github.com/OrangeShark/guile-commonmark/ ) on Fedora 28

I'd like to build it against guile 2.2.2

On Fedora 28 x86_64 there are 2 versions  of Guile

Guile 2.0.14

and

Guile 2.2.2

Guile 2.0.14 is in /usr/bin/guile

Guile 2.2.2 is in /usr/bin/guile2.2

this is what happens

...
configure: checking for guile 2.2
configure: found guile 2.2
checking for guile... /usr/bin/guile
configure: error: found development files for Guile 2.2, but /usr/bin/guile
has effective version 2.0

I'm afraid of removing guile 2.0.14 because it seems that an awful lot of
stuff depends on it

How can I build guile-commonmark against guile 2.2.2 ?

Is this a task for the package author ?

Or can I instruct the build system somehow about which guile to use ?

Thanks in advance
