I use pyqgis to create standalone GIS apps and I want to ask a simple question.
now in my system I have only pythonpath from QGIS `C:\OSGeo4W64\bin\python.exe` I don't have any other python version.
in my installation folder I have a `C:\OSGeo4W64\apps\Python27` and `C:\OSGeo4W64\apps\Python27\Lib\site-packages` folders.

can I install packages in this folders using `pip` ?

for example If I have install standard python and from cmd use pip then I can easy packages on this folder `C:\Python27`.
