CMake non statically sandbox linked build for local development.

**Is your feature request related to a problem? Please describe.**
I want to test/help develop DPG against a non sandboxed application. Using `pip install -e `

**Describe the solution you'd like**
According to discussions this would involve modifying the CMake to have a non statically linked build target.

**Describe alternatives you've considered**
The current alternative is to build and test against a local wheel. Or build in the sandbox with full debugging support.

**Additional context**
Looking for a faster way to iteratively test changes out of the sandbox.
