libudev for cos7

[hmaarrfk]

Is there any reason why this CDT is in "custom-cdt"

cdt-builds/custom_cdts/libudev-devel-cos6-x86_64/meta.yaml

Line 2 in 5b1ebba

name: libudev-devel-cos6-x86_64

Can we move it out of there? It is needed for libusb conda-forge/libusb-feedstock#6

[beckermr]

I don't follow what the issue is.

[hmaarrfk]

i guess then i don't understand why libudev wasn't built for cos7. Is it incompatible?

[beckermr]

I only built the CDTs needed at the time when we migrated from feedstocks to building them all in this repo. If we need more, we should add them.

[hmaarrfk]

great! got it.

[hmaarrfk]

I guess i ran into #40 when I tried to make the PR last night.

[hmaarrfk]

Is it as simply as copy pasting the files and adjusting them as needed?

libudev-devel is provided by systemd-devel in CentOS 7. You could do something like

- {{ cdt('libudev-devel') }}  # [cdt_name=='cos6']
- {{ cdt('systemd-devel') }}  # [cdt_name=='cos7']

Using this suggestion works for libusb and I'd imagine is the way to go for any other packages that might be affected. I think this can be closed.
