Despite having installed libxine-1.1.9.1, I get the following error while compiling a recent SVN version of kdebase (Output of cmake):
==================================================
-- Install the package which contains OpenEXR.pc if you want to support this feature.
-- Create macro to display info at the end of install
CMake Error: Xine_DIR is set to /c/kde-devel/xine-lib-1.1.9.1/, which is not a directory containing XineConfig.cmake
CMake Error: An attempt was made to access a variable: XINE_FOUND that has not been defined. This variable is created by the FIND_PACKAGE command. CMake version 1.6 always converted the variable name to upper-case, but this behavior is no longer the case.  To fix this you might need to set the cache value of CMAKE_BACKWARDS_COMPATIBILITY to 1.6 or less.  If you are writing a CMake listfile, you should change the variable reference to use the case of the argument to FIND_PACKAGE.

-- Found CLucene library: /usr/lib/libclucene.so
=============================================
At the end, cmake complains about having not found xine-libs 1.1.x and the compile stops.

On replacing all XINE_... variables with Xine_ as indicated by CMake in the error message, I get the following error message:

This is using cmake version 2.4-patch 6
