Yep. This is a CMake parsing bug; the regular expression for this is too
greedy (it allows '=' in the variable name). Compare:

> -DPV_EXTRA_CMAKE_ARGS=-DModule_vtkIOXdmf3:BOOL=ON -DBoost_NO_BOOST_CMAKE:BOOL=ON
    |-------------------------------------| |--| |-------------------------------|
                variable                    type            value

versus:

> -DPV_EXTRA_CMAKE_ARGS:STRING=-DModule_vtkIOXdmf3:BOOL=ON -DBoost_NO_BOOST_CMAKE:BOOL=ON
    |-----------------| |----| |--------------------------------------------------------|
          variable       type                        value

this works:

> -DSOME_PATH=C:/path/to/file
    |-------| |-------------|
    variable       value

because paths with '=' are very rare:

> -DSOME_PATH=C:/path/to/file/with/=/sign
    |---------| |-----------------| |---|
      variable         type         value
