An idea, not a solution. You could generate a shell wrapper script together
with each executable where you export all relevant variables. Then you call
the wrapper script instead of the executable, or you would source the
wrapper script.

I guess you are most interested in dynamic library resolution which is
handled by the environment variables:

- LD_LIBRARY_PATH on Linux
- DYLD_LIBRARY_PATH on MacOs
- PATH on Windows

For how to find out all relevant library paths for an application product,
you can get an inspiration from
https://code.qt.io/cgit/qbs/qbs.git/tree/share/qbs/modules/cpp/setuprunenv.js
You might even use these functions as they are.
