Trying to build latest master on Linux

git clone git@github.com:urho3d/Urho3D.git
cd Urho3D
mkdir build
cd build
cmake .. -DURHO3D_SAMPLES=1 -DURHO3D_C++11=1 

CMake Error at Source/ThirdParty/SDL/cmake/macros.cmake:73 (message):
  *** ERROR: Missing Xext.h, maybe you need to install the libxext-dev
  package?
Call Stack (most recent call first):
  Source/ThirdParty/SDL/cmake/sdlchecks.cmake:380 (message_error)
  Source/ThirdParty/SDL/CMakeLists.txt:923 (CheckX11)

I have installed all the libraries mentioned in the docs: libx11-dev libxrandr-dev libasound2-dev and libxext-dev. The header file exists on my machine at /usr/include/X11/extensions/Xext.h. Maybe it’s a problem with FindSDL.cmake?

IF you’re not familiar with cmake and urho3d’s build setup, it’s always recommended to use the provided terminal or batch scripts. Weitjong maintains and updates them regularly for a reason.

Usage: cmake_generic.bat \path\to\build-tree [build-options]

Just cloned moments ago and generated with the same flags and without any issues… (Ubuntu 14.04 LTS 32bit)
