build failure; does not include X11 library path in link

[Davin McCall]

I have just tried to build compiz-0.9.12.0. I encountered several problems, but the first one (which is at least easily worked around) is that the correct library paths for certain X11 libraries are not used when linking. I tried the most straightforward build possible:

    mkdir build
    cd build
    cmake ..
    make VERBOSE=1 2>&1 | tee build.log

I have attached the resulting build.log file. As you can see there is a link failure since the build tries to link against libraries libXrender and libX11, but it does not include the library path (via -L switch). On my system these libraries are in /usr/X11R7/lib, and this is correctly identified by pkg-config:

    $ pkg-config --libs x11
    -L/usr/X11R7/lib -lX11

Obviously this can be worked around be setting LIBRARY_PATH=/usr/X11R7/lib before running 'make', but this should not be necessary.

This particular problem is die to a typo introduced in 2008 and only shows up when someone tries to build Compiz against Xrender development files build into a non-FHS-standard custom location (which explains why it's only being reported now).
