look at latest pybullet for bullet_server

[lucasw]

Is python now a better interface than C++, and bullet_server should support it?

git clone https://github.com/bulletphysics/bullet3.git
mkdir build_bullet3
cd build_bullet3
cmake ../bullet3

../OpenGLWindow/libOpenGLWindow.a(glew.o): In function `_glewInit_GL_ARB_window_pos':
glew.c:(.text+0x7f3): undefined reference to `dlsym'

Try what is in build_cmake_pybullet_double.sh

cmake -DBUILD_PYBULLET=ON -DBUILD_PYBULLET_NUMPY=OFF -DUSE_DOUBLE_PRECISION=ON -DCMAKE_BUILD_TYPE=Release ../bullet3

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
PYTHON_LIBRARY (ADVANCED)
    linked by target "pybullet" in directory /home/lucasw/other2/bullet3/examples/pybullet

Run cmake-gui and set PYTHON_LIBRARY to /usr/lib/x86_64-linux-gnu/libpython2.7.so

Now it builds.
