Why is this project clang++ only?

[maaku]

The CMakeLists.txt file requires the use of clang. Why? Clang is not installed by default on all operating systems, and I was able to get it running easily enough with GCC ( see #1 ).

This seems like an explicit choice, however, which makes me wonder why. If there is a deeper incompatibility it should be documented. If there isn't, that build restriction ought to be removed.

Not much, no. I switch occasionally to make sure nothing funny is going on, such as the errors you ran into, but I strongly prefer dealing with clang these days.
