PCL library setup using vcpkg seems to be missing include files (pcl/visualization in particular)

My goal is to visualize a point cloud using PCL. This is possible according to their official tutorial (link). In the tutorial there is an include path pointing to cloud_viewer.h file (located under visualization folder). After a vcpkg install using "vcpkg install pcl:x64-windows" I couldn’t find the visualization folder. After some research it I found out that "visualization" does not come with default PCL install, but it is an optional feature (link). Then I used the "vcpkg install pcl[vtk]:x64-windows --featurepackages" and I am still missing the needed folder. If anyone could point out to me where am I making a mistake I would appreciate it.
I got the same problem with you. It seems vcpkg is not a good choice for pcl library. Many people have the same problem with visualization module
Using vcpkg does not provide all files, includes and headers for pcl.
I had the same issue, and downloading pcl all in one solved it.
You can find it here for example: http://unanancyowen.com/en/pcl181/
Other thing that can help, is to use this command on vcpkg:
.\vcpkg install pcl:x64-windows-static

What IDE to use to start contributing code for CKEditor?

It's my first question here on stackoverflow so please be easy on me.
I've been trying to set up the source for CKEditor so I can start contributing to this editor. I have followed this link: http://docs.ckeditor.com/#!/guide/dev_contributing_code but I got stuck on step 4 as I haven't got the following file: bender.js. I also need something called gruntfile for step 5. Do you know where I can get them from as when I fork https://github.com/ckeditor/ckeditor-dev, the following project does not come with them. Also, what IDE do I need to use to develop code? Sorry, for this question as it might seem a bit stupid but I come from the Java background and Node.js is really new to me, therefore I'm struggling a bit here.
Thanks for any help
There are no requirements regarding IDE, at the end it's all just text.
Regarding your problems: Make sure you're forking ckeditor-dev, and not ckeditor-releases repository. Only dev repository contains all the helpers like gruntfile.
The gruntfile is there so if you cloned CKEditor repository, you must have it.
Then all you need to do is follow up the instructions of CKEditor contribution guide closesly, and you're good to go!

Xcode gtest.h not found

I have followed the google's installation guide here.
The build fails because gtest/gtest.h is not found.
After debugging his problem with him, we decided to go old fashioned with cmake instead of using a framework bundle, and now all is working well.

How to setup OpenACS?

I am trying to setup OpenACS Project. I tried some Open Source Projects available on net. I am trying to setup OpenACS from below link.
http://sourceforge.net/projects/OpenACS
But it is showing inactive and code is not there. Can i found this code somewhere else.
Your link points to the "Automatic Configuration Server" (ACS), a project that unfortunately has a name-clash with the Open Architecture Community System (OpenACS). If you are referring to the latter, here you go:
http://openacs.org/xowiki/openacs-system-install
You can find the official OpenACS code here: http://openacs.org/news/item?item_id=4197887
Two great installer scripts are located at github: https://github.com/gustafn/install-ns. It works great to get you up and running with a simple NaviServer, PostgreSQL OpenACS installation.
This should get you started!
http://sourceforge.net/projects/OpenACS has a fork https://sourceforge.net/projects/libreacs/ and several its clones on github (I don't actually know which one is official). You'll find minimal installation instructions in acs/doc/README after cloning e.g.:
git clone https://git.code.sf.net/p/libreacs/code libreacs-code

Boost documentation problem

I'm trying to view the boost documentation at their website: http://www.boost.org/doc/
But it says Forbidden.
Any way I can download the documentation, or get past this error?
I'm getting a similar error from the front page for the link to the docs. However I vaguely remember that if you download the boost libraries, the tarball/zip contains a copy of the docs.
We've had some hosting problems related to the Boost documentation. Things should get resolved really soon. In fact at least the docs for the latest 2 releases are already up again (for me), see http://www.boost.org/doc/.
