How to build in a sub directory?

[ghost]

I want to test with both Clang and GCC. Currently, I have to keep two versions of the eepp source tree: eepp-gcc and eepp-llvm. I'm totally lacking experience with premake. But with CMake, it's very easy. You only need one source tree. You can create different build directories (e.g., build-gcc, build-clang,...) to build with different configurations.

It's not possible with the current build configuration. This is not something that premake provides in a direct way. Paths are basically defined in the premake files by the developer.
