The -isysroot option should come from Qt, gathered by configure from the 
qmake output. Probably Qt5 was build with 10.11 sdk. I'm not sure. However 
independently of what is your running OS I was meaning that the headers of 
Big Sur should have changed, because there is no such problems with SDKs from 
previous systems (e.g. Catilina). 

To investigate the issue you can use a very simple Qt application and try to 
build it with qmake to see which headers are used. As I said, the error 
messages you get seems to come from changes in the headers which cause symbol 
clashes in TeXmacs. We had this kind of issues before due to the fact that 
various libraries might have incompatible #define
