Qt. Automatically adding version for application
qmake, qt
Solution
If you can get the version from a shell command, you can assign it to the variable with the `$$system` qmake function.
So, for mercurial, you could try:
# if the version tag is <major version>.<minor version>
VERSION = $$system(hg parents --template '{latesttag}.{latesttagdistance}')
# or if you fill all 3 positions manually: <major>.<minor>.<patchset>
VERSION = $$system(hg parents --template '{latesttag}')
Or if you are using the local revision number as the version:
VERSION = $$system(hg parents --template '{rev}')
which will only print that number without the uncommitted change indicator ('+').
Problem
In a `.pro` file, I can set version of application such: ``` VERSION = <some version> ``` Is there a way of doing this automatically (e.g. getting the value from Mercurial)?
