I am working on the development of a set of libraries. The core of the code is LGPL, but it includes several optional modules that require proprietary libraries. The problem with the modules using proprietary libraries is that the company that owns those libraries requies a license agreement stating that we will not distribute any of our own code that includes any of their headers, calls any of their functions, etc. except to other licensees of their library. So we'd like to distribute our library source both with and without our source for accessing the proprietary libraries. So our source tree will have optinion subdirectories. Is there any way to define things such that automake a) doesn't fail when it cannot find the Makefile.am and b) ignores entiries in the SUBDIRS (in the Makefile.am in the parent directory) for subdirs that do not exist?
thanks, - jason
