osx build notes

[hyarion]

Here are some notes on how I got it up and running on osx (10.10.4) using homebrew to install the required dependencies.

First we need to install oce but due to recent changes to clang we need to build a debug version of oce (more on why here: http://tracker.dev.opencascade.org/view.php?id=26042 )

To do this, edit homebrew-science' oce formula so it looks like this: http://pastebin.com/S3vjFNVv (based on https://github.com/Homebrew/homebrew-science/issues/2764 )
brew edit homebrew/science/oce

Install modified formula
brew install oce --build-from-source
...go do something else while waiting...

Export the path so cmake can find oce when building the kicad_oce_3D plugin
export CMAKE_PREFIX_PATH=/usr/local/opt/oce

Install the rest of the requirements:
brew install wxwidgets glm

Build kicad_oce_3D
mkdir build && cd build && cmake .. && make

Download and install 3d_initial_merge branch of kicad.
This one is old but works good enough to test if kicad_oce_3D works: http://downloads.kicad-pcb.org/osx/testing/3d_initial_merge/

Copy plugin
cp kicad/kicad.app/3d/libs3d_plugin_oce.so /Application/Kicad/KiCad.app/Contents/PlugIns/3d/
and libraries to kicad
cp kicad/kicad.app/Contents/Frameworks/libkicad_3dsg* /Applications/Kicad/kicad.app/Contents/Frameworks/
