How to deploy headers and then make them readonly from qmake and qtcreator?

[gbonnema]

I deploy my libraries to a specific set of 'lib' and 'include' directory. I would like to ensure that if I use these header files from a different project I do not accidentally modify the deployed header files, because they will be overwritten the next time I deploy, plus this creates discrepancy with the library.

How can I make deployed header files readonly using qmake?

As I share this environment with the other members of my team, I would prefer to solve this from qtmake, in stead of doing something on my machine only. I distribute using git.

Anyone ideas?

An example of a .pro file is:

@QT -= qt
QT -= core gui

TARGET = bitpowder
TEMPLATE = lib

CONFIG += C++11
CONFIG += create_prl
CONFIG += link_prt
CONFIG += static dll

DEFINES += BITPOWDER_LIBRARY

# just a few example source files

SOURCES +=
dispatch.cpp
stringparse.cpp
thread.cpp
type_hash.cpp \

# just a few example source files

HEADERS +=
bitpowder_global.h
dispatch.h
stringparse.h
thread.h
type_hash.h
zip.h
