Thanks for your comments Oscar.
Our current thinking is to post process the cmake generated files
and remove
all the absolute paths (since the project files are simply text).
Since
cmake is a black box to me (and I am unfamiliar with it's generated
'code'),
it's unclear if this a 'good' idea? Or will I bump into other
gotcha's?
Any advice is appreciated...you have a lot more experience with
this than I
do!
Steve, if that was a good idea, CMake would be doing that by default
instead of using absolute paths, don't you think?
Sure, but any cross platform tool has the constraint that it needs to
deal with the "lowest common denominator" (which might be difficult).
As a result, it could be the case that using relative paths for Visual
Studio (just to take an example) might be simpler than using relative
paths when generating Unix 'make' files.
As Eric pointed out, you must add CMake to your compiler build chain.
It's one more tool (and with no third-party dependencies), like the C
preprocessor, the C compiler and the linker. We did that at work and
it's no big deal, people are so happy with the pro's of CMake over our
former buildsystem (Visual C++ projects for Windows and Makefiles for
Unix, which required twice the amount of maintainance work), they are
not looking back.
As I said in my initial post, we love CMake for development (since
llvm/clang are cross platform). Developers understand the benefits of
'cmake'. Unfortunately, developers aren't the only clients building
llvm/clang.
In any event, maybe adding CMake to our build chain isn't such a big
deal.
Just trying to get the collective wisdom of this group before we make
any changes.
Thanks for your input,
snaroff
