Fixes#17.
Stage 2 is fairly minimal, stage 3 builds/installs OpenCV and WPILib et al, and stage 4
builds/installs the FRCVision webdash and adds the vision examples.
Other changes:
- OpenCV compiled with ffmpeg, OpenBLAS, and libgtk (fixes#79, fixes#80)
- OpenBLAS added to image (fixes#65)
- C++ Makefile is more easily extensible (fixes#71)
- Sources for everything are bundled into image into /usr/src
- README updated (fixes#16)
- pkg-config files for wpilibc et al are now installed and C++ Makefile uses them (if compiled local to Pi)
- Both dynamic and static libs are included in image
The only downside of all these changes (particularly the ffmpeg, OpenBLAS, and libgtk inclusion)
is the image size is now over 3GB (800MB compressed). The previous image didn't quite fit on a
2GB card however.
* Move java lib install to /usr/local/frc/java
* Build and install both debug and normal OpenCV libraries
* Install OpenCV cmake files
* Build OpenCV Java with version 8 target
* Build static OpenCV for static allwpilib binaries
* Move netconsoleTee install to /usr/local/frc/bin
* Move multiCameraServer default app install to /usr/local/frc/bin
* Install more FRC binaries
* Fix /home/pi/zips/java-multiCameraServer.zip owner to pi:pi
* Remove azure 60 minute timeout
* Add openjdk-8-jdk to Azure docker image (this is needed for cmake to find javah as only cmake 3.9 is available)
