Can you share the build commands you are using to build coin? Please add the information about platform and compiler you're using. When using CMake COIN_DATADIR should be set to the contents of CMAKE_INSTALL_DATADIR when processing the file src\config.h.cmake.in in src\CMakeLists.txt.

I get the same error using Visual Studio 2010. I did not run any cmake command.
