Out-of-source build doesn't work out of box

[eustas]

[at least for brotli] current directory is not used as a destination of generated build files.
Scenario like this won't work as expected:
mkdir out && cd out && ../configure
A hack is required to fix behaviour:
mkdir out && cd out && ../configure --pass-thru -B.

Can you be more specific? That's how I always build stuff with this script and it always works. I also just tried dropping a copy of this script in my brotli tree, and it works as expected.

[eustas]

Oh, the things break only if someone occasionally runs ./configure in root project folder.
After this CMake sticks to root folder, unless -B. is specified (because of CMakeCache.txt file).

[nemequ]

Ah, that makes sense.

I don't see the -B flag documented anywhere, where are you getting that? It's not in cmake(1)… If that's something we could add to the cmake command without causing problems I'd be willing to do so, but this seems like more of a CMake problem, and they don't seem interested in fixing it.
