My Git repo was cloned from the offical TeXworks SVN repository, the
texworks-svn branch is currently tracking your trunk. If I disappear and
someone wants to use my CMake patches on top of the newest version of the
SVN repo, the following workflow should do the trick:
# Clone the Git repository:
git clone git://github.com/Sharpie/TeXworks.git
cd TeXworks
# Add the TeXworks svn repository, remove the `trunk` part and
add --stdlayout if you want to bring in branches and tags from SVN.
git svn init http://texworks.googlecode.com/svn/trunk/
# Bring in SVN history (this will take a while)
git svn fetch
# Checkout the SVN trunk as a git branch
git checkout -b texworks-upstream remotes/git-svn
# Checkout the CMake branch
git checkout cmake-only
# Forward-port all changes in cmake-only onto the the SVN trunk:
git rebase texworks-upstream
# If new changes occur in SVN:
git checkout texworks-upstream
git svn rebase
git checkout cmake-only
git rebase texworks-upstream

Sure, I'll just have to import the tags directory into the Git repository.

Yes, Homebrew builds quite a few projects that use CMake. However, it does
have a policy that frowns on including Applications unless they have a lot
of dependencies or are otherwise difficult to obtain.

Gah. Bad copy and paste job, the correct url is:

Looks great! I'll pull your changes over, when I get the chance. One thing
you may be interested in is that CPack can be set to build Debian packages
and RPMs on Linux.
To generate separate pull requests, you have to adopt the "branching
mindset" that git is famous (infamous?) for. Basically, it works like this:
# If there is another upstream repo you want to get updates from
get remote add upstream git://github.com/Sharpie/TeXworks.git
# Check out the master branch and sync it with "upstream"
git checkout master
git pull upstream master
# If any conflicts happen:
git mergetool
# Create a new branch for a feature that will start out as a copy of the
master branch:
git branch feature-x master
# Switch to the feature-x branch
git checkout feature-x
# Hack Hack Hack
# Push some feature brances to GitHub
git push origin feature-x feature-y
Now to open a pull request, go to your project page on GitHub.com, select
the desired branch from the "Switch Branches" menu and then hit the "Pull
Request" button. The resulting request will only contain commits from the
branch you selected.
Or, to do it the ol' fashioned way:
# Create patchfiles containing all the commits that happened on the
feature-x branch relative to your master branch
git format-patch master...feature-x
# Or a given remote master branch
git fetch upstream # Make sure git has an up-to-date picture of the
upstream repo
git format-patch upstream/master...feature-x

No problem, I will try to keep the cmake-only branch limited to changes
that concern the build system--i.e. by excluding things like the README swap
I did for the GitHub project page. That way a GitHub comparison between
texworks-svn and cmake-only should always generate a nice patch if you
decide to bring it into the main repo.

The problem that is occurring for me is that when QT4_WRAP_CPP processes
TWApp.h to generate moc_TWApp.cxx, it runs the following command:
cd /Users/sharpie/code/TeX/texworks/build/src &&
/usr/local/Cellar/qt/4.7.3/bin/moc -I/usr/local/Cellar/qt/4.7.3/include
-F/usr/local/Cellar/qt/4.7.3/lib
-I/usr/local/Cellar/qt/4.7.3/lib/QtScript.framework/Headers
-I/usr/local/Cellar/qt/4.7.3/include/QtUiTools
-I/usr/local/Cellar/qt/4.7.3/lib/QtScriptTools.framework/Headers
-I/usr/local/Cellar/qt/4.7.3/lib/QtGui.framework/Headers
-I/usr/local/Cellar/qt/4.7.3/lib/QtXml.framework/Headers
-I/usr/local/Cellar/qt/4.7.3/lib/QtCore.framework/Headers
-I/Users/sharpie/code/TeX/texworks/src
-I/Users/sharpie/code/TeX/texworks/build/src -I/usr/local/include/hunspell
-I/usr/local/include/poppler
-I/usr/local/Cellar/poppler/0.16.5/include/poppler/qt4 -I/usr/X11R6/include
-I/usr/include -DQT_SCRIPT_LIB -DQT_UITOOLS_LIB -DQT_SCRIPTTOOLS_LIB
-DQT_GUI_LIB -DQT_XML_LIB -DQT_CORE_LIB -o
/Users/sharpie/code/TeX/texworks/build/src/moc_TWApp.cxx
/Users/sharpie/code/TeX/texworks/src/TWApp.h
Somehow, that command apparently processes TWApp with Q_WS_X11 defined which
causes the D-Bus dependencies to show up. I don't think REMOVE_DEFINITIONS(
-DQ_WS_X11 ) would be a solution because CMake is not passing -DQ_WS_X11. It
seems likely that one of the Qt header files is setting the definition. I'm
by no means an expert on Qt, but it seems likely that Q_WS_X11 could be
defined for Mac since X11 is present on my machine.
One thing that I may try is running QT4_AUTOMOC on the `*.cpp` files instead
of QT4_WRAP_CPP on the headers to see if it makes a difference.
Hope this is useful to someone!
