Issuess on Manjaro distribution with MIME types

[phdxpahob]

Hello everyone!

I am using Manjaro linux, but as far as I know it is tightly based on Arch, so it should have the same issue; given that it is not critical to compilation probably it's not reported yet.

When I build the package with yay/makepkg and installing it, it gives the following output:

$ sudo pacman -U camotics-git-r954.c0072b6-2-x86_64.pkg.tar.zst

Which is not a critical error but somehow it is not "clean" install.

To resolve this issue one must either correct it manually in /usr/share/mime/packages/ to remove the directory and rename the file mime.xml with it, or go to the build directory and modify SConstruct, line 285:

285 - env.Install(prefix + '/share/mime/packages/camotics.xml', 'mime.xml')
285 + env.Install(prefix + '/share/mime/packages', 'camotics.xml')

This resolves the failure to update the MIME database on package installation(s).

Since I'm not sure how it is on other distributions (even variants of Arch based), I'm posting here for discussion. Also, please notify me if addtional information is required.

I updated the Arch aur package with this patch. It should install clean now.
