I'm trying to figure out the best way to handle something that was a convenience lib under autotools. I realize that there's a FAQ entry here:
https://cmake.org/Wiki/CMake_FAQ#Does_CMake_support_.22convenience.22_libraries.3F But its terse 2 paragraphs don't say how to actually do what it suggests. My problem is this. I have this source tree: lib |--foo.c |--foo.h |--bar.c |--bar.h |--baz.c src |--goo.c In lib, I need to somehow collectively refer to foo and bar. Okay, so I can create a variable: set(foobarSRCS foo.c bar.c) set(foobarLIBS ${externalLibFound}) which is what the FAQ entry seems to suggest. However, this variable is not visible to goo.c. Okay, so as an alternative, I can do this: set(foobarSRCS foo.c bar.c PARENT_SCOPE), etc. but now the variable is not visible to baz.c, which also must include the srcs to create a module library called _baz! I can of course do something like this: set(foobarSRCSLOC foo.c bar.c) set(foobarSRCS ${foobarSRCSLOC} PARENT_SCOPE) but this feels dirty and repetitive. I also realize that I can just create the variables in src, but that kind of defeats the entire purpose of walling of the common libs and their dependencies in the first place. Is this the right way to work, or am I missing something simple? --Jack
