Use easytags with a local installation of ctags

[SKOHscripts]

I’m currently using a local version of ctags, and the command I use to generate tags is like
~/ctags/bin/ctags -R --exclude=Makefile
I thought easytags could answer my need but it does not run at all, saying that ctags are not installed. Here is what I put in the vimrc

" EASY TAGS
let g:easytags_cmd = '~/ctags/bin/ctags'
let g:easytags_async=1
let g:easytags_file = '~/work/tags'
let g:easytags_events = ['BufWritePost']
let g:easytags_autorecurse = 1
let g:easytags_resolve_links = 1
let g:easytags_suppress_ctags_warning = 1

Do someone has the same pb? What could I do because I can’t install ctags on my debian10.
