Correct cmake variables

* correct cmake install target condition

The cmake variable BUILD_INSTALLER was renamed to
MATPLOTPP_BUILD_INSTALLER, but it was not updated in
source/matplot/CMakeLists.txt. As a result Matplot++ was not installed
completely via cmake install target with cmake presets provided.

This patch completes the renaming and now cmake install works as
expected.

* correct more cmake variable names after rename

I found more variables that seemed to be missed by the recent renaming.
This patch completes renaming of variables:
  - BUILD_FOR_DOCUMENTATION_IMAGES
  - BUILD_HIGH_RESOLUTION_WORLD_MAP
  - BUILD_WITH_PEDANTIC_WARNINGS
  - BUILD_EXPERIMENTAL_OPENGL_BACKEND
