"First run" support
A new kdesrc-build user should be able to easily have kdesrc-build take even their minimal base distribution install to having all the right distro dependencies installed to allow kdesrc-build to work and KF5/Plasma5 and major apps to build.
- Installing needed Perl modules from only a minimal base Perl
- Installing CMake, gcc, etc. (the build deps)
- Installing system Qt
- Installing KDE dependencies (from extra-cmake-modules on)
- .bashrc setup to integrate kdesrc-build and the new environment variables (as part of kdesrc-build-setup?)
