So you want to build just a part of boost, right ? > specify this (or is it possible) in cmake. I also made refrence to a > namespace issue above which no one has answered.

You could add an add_custom_target(foo) and then use add_dependencies(foo lib1 lib2), and then building foo will just build the libs it depends on. But maybe this is what BUILD_PROJECTS does ?
