 on Windows 10, current trunk, I normally execute the following two Cmake
 commands:
 mingw32-make -j 2
 mingw32-make install
 
 The time required for this is 300 seconds, 150 seconds for each step. This
 time is the same no matter how small the change, even if I just insert one
 single blank character somewhere.
 Previously, using btool, the total time required for this would be about 10
 seconds or so, for a complete rebuild of Inkscape.
 So CMake is about 30 times slower than btool, which makes it almost
 impossible to do diagnostic work with Inkscape, any way of speeding it up?

At least with "make" you can speed that up a bit by running 

mingw32-make -j2 install

right away. It will build everything that needs to be build and you save one 
pass of dependency checking. Not sure about ninja, but I would guess it 
behaves similar.
