I had this problem recently, when some files were not being found
because qmake was generating targets with the wrong path to clang.

I remember that somewhere during the makefile generation qmake runs
xcrun --find clang
and uses the output as the compiler path, ignoring what you set in
QMAKE_CXX.
Can’t remember where it does that now, but the fix for me was
to hardcode the the paths in the mkspecs/common/clang.conf file
(QMAKE_CXX and QMAKE_CC variables).

Hope that helps.
