Build fails: Swig source step of building PyTrilinos fails with execvp: /bin/sh: Argument list too long

Current Behavior

I am trying to build Trilinos 12.10.1 with python support. I ran into this issue (https://github.com/trilinos/Trilinos/issues/2434) where the build fails with an error 'execvp: /bin/sh: Argument list too long'. I fixed that by setting the suggested

CMAKE_CXX_USE_RESPONSE_FILE_FOR_OBJECTS=ON
CMAKE_CXX_USE_RESPONSE_FILE_FOR_INCLUDES=ON
CMAKE_CXX_USE_RESPONSE_FILE_FOR_LIBRARIES=ON

Which works well for the compilation part. However, the 'Swig source' step triggers the same error message, and clearly, doesn't respect these CMake flags.

Possible Solution

Other then shortening the prefix on my end (which is tricky because I use EasyBuild as a build system, which produces somewhat long prefixes), is there anything that could be done on your end to fix this issue?

I can imagine even a shorter prefix is just a temporary relief, as future versions may trigger even more includes. Thus, I think a more permanent solution for these excessively long command lines may be needed on your end anyway.

Steps to Reproduce

To reproduce: pick a long enough prefix (and possibly build enough of Trilinos' components to get a long link line).
