Cannot build on OS X El Capitan

[shpsec-dennis]

Hi,

I can't seem to build most of the targets on El Capitan.

$ cmake --version
cmake version 3.5.20160411-g9ac11

CMake suite maintained and supported by Kitware (kitware.com/cmake)

$ cmake .

  MACOSX_RPATH is not specified for the following targets:

tools.jar is probably not found at the place the build is expecting it. Can you try adopting CMakeLists.txt to use the path where it is available at your computer. You need to change this line:

set(CMAKE_JAVA_INCLUDE_PATH ${JAVA_INCLUDE_PATH}/../lib/tools.jar)

FWIW this makes it compile, not sure if it will work yet:

Just saw the tools.jar comment. I received that error before and I set this manually and then I got a slew of different errors, I posted what I needed to do above, but I did adapt the CMake file, though in a hacky fashion: +set(CMAKE_JAVA_INCLUDE_PATH /Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home/lib/tools.jar)
