Environment setup help

[HxriM]

Hi!
I am developing in a Devcontainer and I need to source a complex environment file to get my toolchain set up properly.
Whats the best way to accomplish this? I can add it to the bashrc or /etc/profile but those files dont seem to be used by the CMake process. When starting CMake is it possible to instruct the Extension to use a login/interactive shell so these files can be accessed?

Have you considered using CMakePresets.json, where you can explicitly set your toolchain file as well as setting up your environment in the environment field of a Configure Preset?
