[CMake] A configure script solution

[Mike Jackson]

One way to get the "optional" packages compiled is to add something  
like the following to your cmakelists.txt file:


OPTION(BUILD_FOO "Option to build Foo subproject" ON)
OPTION(BUILD_BAR "option to build Bar subproject" OFF)

IF (BUILD_FOO)
ADD_SUBDIRECTORY( ${Foo_Dir} )
ENDIF (BUILD_FOO)

IF (BUILD_BAR)
ADD_SUBDIRECTORY(${Bar_DIR} )
ENDIF (BUILD_BAR)

Then, if you _really_ wanted to, you could have a simple bash script  
which lets someone set these values by taking arguments then passing  
those to cmake using the -Dlibdir="your/path/to/lib" syntax. Just  
running ccmake is probably quicker although can not be "automated".

Just my 2 cents..
