Incorrect __init__.py script installed when not using catkin_make

[jbrindza]

If you compile and install a package that contains python source code and messages the <package_name>/__init__.py file from the devel space gets installed into the install space overwriting the previously installed __init__.py from the source.

You can recreate this problem by building dynamic_reconfigure with catkin_make_isolated. The install_isolated/lib/python2.7/dist-packages/dynamic_reconfigure/__init__.py file is the one from devel_isolated/dynamic_reconfigure/lib/python2.7/dist-packages/dynamic_reconfigure/__init__.py.

I believe it is due to the install regex rule for installing __init__.py files from subdirectories. I assume this rule is matching <pkg_name>/./__init__.py

 install(
 DIRECTORY ${CATKIN_DEVEL_PREFIX}/${@(l)_INSTALL_DIR}/@pkg_name
 DESTINATION ${@(l)_INSTALL_DIR}
 FILES_MATCHING
 REGEX "${CATKIN_DEVEL_PREFIX}/${@(l)_INSTALL_DIR}/@(pkg_name)/.+/__init__.pyc?$"
 )

Strangely, this does not happen with catkin_make, I don't understand why its different.

Same behaviour using cmake version 2.8.12.2 and 2.8.7

The problem should have been addressed some time ago with #38. Can you please mention with which genmsg version on what ROS distribution you are having the problem?

Sorry about that, looks like I was using an old version. Updating to the latest version fixed the issue. Thanks.
