Previously when generating the HackStudio CMake build file,
we used all dependency libraries that are specified in
target_link_libraries commands as the dependencies of a library.
The recent addition of LibCryptSHA2 broke things because that library
is not declared with serenity_lib like most other libraries
(it uses special linking properties).
This means that we don't declare it in the CMake file we generate.
To fix this, we now filter the dependencies and only include libraries
that we define in the build CMake file.
ProjectBuilder takes care of building and running the current project
from Hack Studio.
The existing functionality of building javascript and Makefile projects
remains, and in addition to it the ability to build standalone serenity
components is added.
If the Hack Studio project is the serenity repository itself,
ProjectBuilder will attempt building the component that the currently
active file belongs to.
It does so by creating a new CMake file which adds the component as a
build subdirectory.
It also parses all CMake files in the serenity repository to gather all
available libraries. It declares the libraries and their dependencies in
this CMake file.
It then uses the HACKSTUDIO_BUILD CMake option to direct the build
system to use this CMake file instead of doing a full system build.
