error with conan packages for OS X

[Sean Ryan]

There are the 2 problems described below during building/execution on Mac ( the second problem is first as it is a smaller description ).

Steps to Reproduce:
-------------------
conan remote add worldforge https://api.bintray.com/conan/worldforge/worldforge-conan
git clone <email address hidden>:worldforge/ember.git
cd ember
mkdir build && cd build
conan install .. --build missing
cmake -DCMAKE_INSTALL_PREFIX=/Users/sryan/code/wf ..
make -j all install media-download
cd ../..
bin/ember

OUTPUT:
-------
pandora:wf sryan$ bin/ember
Starting Ember version 0.7.2-1098-g78b631c10 with prefix '/Users/sryan/code/wf'.

======================
Problem #2: OPENGL3 is not supported on mac.
======================
Description: As you can see from the conan package, only the OGRE GL3PlusStatic render system is included, and by default OSX does not support this. I don't know conan enough to investigate more, but I did not notice anything in the details I saw, but I would recommend that on OSX that either the OpenGL 2.x plugin and/or the Metal render plugin be build instead of the GL3 one.

======================
Problem #1: There are references that appear to be hardcoded in the conan packages to '/Users/travis', which is not valid as having a Travis user installed/created is not an ember requirement.
======================
Description: Looks like this is the same in most if not all the comments, below is the error after this reporting "image not found". I was able to work-around this by doing a symlink of /Users/sryan -> /Users/travis After working around this, there was problem #2.

[Sean Ryan (sryan)]

In order to address problem #2, trying to rebuild the conan packages ... using:

conan install .. --build=*@worldforge/stable

Results in below. The cause of course, is that autoconf is not installed ( which it is not for OSX ... you need something like brew/macports ).

Per our glitter msg, seems like xdg should not be selected on that platform? This would indicate to me that either the pre-reqs are not valid ( i.e. you need to install brew/macports with [package list] ... which is fine, but definitely not a native mac option and needs to be stated up-front; or there is a recipe issue somehow ).

Thoughts?
