ccmake: Improve coloring, allow customization
Change the default color for strings from BLUE
(which is nearly illegible on any terminals using the standard color palette which has been around since at least CGA, almost 40 years ago) to CYAN
. Add ability to customize the colors via an environment variable (inspired by LS_COLORS
and using similar syntax).
Fixes: #20596 (closed)
