When I do:

./configure --prefix=/opt/trinity --enable-closure

I get:
Detected TQt4...
configure: error: Qt (>= Qt 4.3 and < 5.0) (headers and libraries) not 
found. Please check your installation!

--enable-closure adjusts KDE_USE_CLOSURE_TRUE, KDE_USE_CLOSURE_FALSE and 
KDE_NO_UNDEFINED.   The first two are not used in kdeadmin.  The third 
sets the linker to "-Wl,--no-undefined -Wl,--allow-shlib-undefined". 
That fixes the need to use LDFLAGS, but it doesn't help detect 
dcopidl2cpp and dcopidl2cpp.


CPPFLAGS='-I/opt/trinity/include/tqt' \
   ./configure --prefix=/opt/trinity --enable-closure
make TQTDCOPIDL=dcopidl2cpp TQTDCOPIDL2CPP=dcopidl2cpp

now works.  I suppose I could use:
  export CPLUS_INCLUDE_PATH='/opt/trinity/include/tqt'
  ./configure --prefix=/opt/trinity --enable-closure
as an alternative to CPPFLAGS.

And yes, the instructions for 3.5.10 worked fine without hacks:
