Is it ok to set this to build*/ so that we can have multiple builds? Thanks.

It might be a problem if a folder in PCL is named 'building' etc..
It's not a good idea in my opinion.

Here is a little trick; Put this in your .gitignore :

build/
my_second_build/
my_third_build/
.gitgnore

This way gitignore will ignore .gitgnore... 😄

I mean build*/, not *build/. With build*/, we can have builds like:

build/
build-debug/
build-release/

This won't be a problem if a file in PCL is named 'blablabuild"

By the way, it's great to make gitignore ignore .gitgnore 👍

I updated my comment too, building is a problem if it is a folder!

[xiangxw]

yes, you are right. thanks. 😄

I have build dirs outside of the git repo (on an SSD) and different names as well. As it's hard to predict the name and on the other and easy to just have a gitignore locally, I vote against this pull request.

The official instructions makes the user create a build folder inside PCL git repo:

Well it's not a big deal; if you don't want it let's drop the idea

It's only my vote, if others want it, I'm ok as well ;).

There is a special file where you can put your own ignores: .git/info/exclude.

I'm also against. If it was the case that absolutely everyone uses build/, then it would make sense. But from this discussion it is obvious that that is not the case.
