True. Fixed this.

I wasn't aware of this (although Adolfo might have warned me about this).

I'll adapt the orocreate-pkg template then to use the all-caps version.

I'm not against this, but I won't maintain it or develop it.

We have another solution ready for 2.3, using the UseOrocos.cmake macros. We
process the manifest.xml file, lookup all dependencies' .pc file and set the
include and linking flags. We depend on xpath to parse the manifest.xml file in
case rospack is not available.

In turn, a .pc file is generated for your package which others can use by
listing the package in their manifest.xml file.

This is on my toolchain-2.2-newlayout branch on github, as I announce a month
ago.
