[CMake] on find_package and building dependencies

[Ryan Lewis]

Hi,

I really like CMake's find_package() utility for finding dependencies,
but for some projects I have a
separate local copy of the installed libraries, and I want to point
find_package at a particular directory to find the installed
libraries.
How can I do this?

On that note, I also have some dependencies which themselves are build
using CMake, it is possible to tell my CMake Project to
build another CMake project?

Thanks,
