Update build scripts

[jchristopherson]

This pull request addresses the installation issue discovered by @vmagnin. The issue was traced back to the CMake scripts in the forimage library. I have submitted a pull request fixing that issue. Once that pull request is merged into main, this request should complete the fix.

Thanks @jchristopherson.
I have tested the ForImage examples and ForColormap examples, as well as the ForColormap test, and they function correctly on my system!
