As discussed in 0011689:0024625 it is not a CMake limitation. It is a GNU make limitation and probably others. Using characters in the path considered special by Make tools is just asking for trouble. CMake is just warning early about it.

If anyone can prove me wrong with a patch I'd love to accept it. Otherwise I do not plan on spending time for this.

On second thought the cases where CMake has to generate a full path on the left hand side of a Make dependency are fairly obscure. Rejecting *all* paths with '=' in them is perhaps too heavy-handed to avoid them.

Perhaps this is better behavior:

I'm not sure this is completely fixed. Please see the "It Didn't Work! > Windows" section at https://github.com/ryppl/ryppl/wiki/Setting-up-a-Ryppl-test/f10de6d5a88708b17b136e73f529ee272bc4c087 [^]

The only "fix" here was to stop complaining arbitrarily for '=' in the path. No one claimed that '=' is *supported*, as 0011689 is still not possible to fix due to native Make tool limitations.

I see. Well I guess there's a limitation in MSBuild as well.

Re 0012934:0029601: In order to confirm that it is a native tool limitation and not an escaping problem we need a msbuild-only test case like the one for make in 0011689:0024625.

Good news for the Makefile generators. It is possible to support '=' after all:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=ee6c1b8a [^]

This won't help for the VS/MSBuild case though.

Sending issues I'm not actively working on to the backlog to await someone with time for them.

If an issue you care about is sent to the backlog when you feel it should have been addressed in a different manner, please bring it up on the CMake mailing list for discussion. Sign up for the mailing list here, if you're not already on it:

 http://www.cmake.org/mailman/listinfo/cmake [^]

It's easy to re-activate a bug here if you can find a CMake developer or contributor who has the bandwidth to take it on.
