As an update to my question, I'd like to add that I now found out that apparently emcmake ignores or forgets all environment variables set within the shell, unless you specifically specify them on the emcmake command line, again! Armed with this knowledge, I was able to build FreeType and then Opencascade. However, I still run into same the problem when trying to build the webGL sample: for some reason, even passing the environment variables to the FreeType dirs doesn't help. Maybe other variables are needed here, but it's impossible to figure out what is missing.
I should point out that I haven't worked with *ix and makefiles for 30 years, and although I got plenty of advice from colleagues, it's still possible I did not execute the build and install commands as expected by emscripten. If someone could post the exact commands needed to build and install a package with emscripten using the ubuntu bash shell (inside a Docker environment), that could be very helpful - maybe that would help me create the missing .cmake files?
