Does that happen on a fresh buildtree, or do you already have something in the cache (CMakeCache.txt) ?

Yes, it's a fresh build.

Which generator are you using ?

I tried MinGW Makefiles and Visual Studio 10/11, none of them worked. Here's the output from the MinGW one:

The C compiler identification is GNU 4.8.0

Interestingly, VS10 generator printed a weird error during configuration:

Forgive my stupidness, it turns out I forgot to add yasm to the system PATH!

Though I must admit the contents of the CMAKE_ASM_NASM_COMPILER variable are somewhat misleading. Shouldn't it be set to an empty string on error?

No, it's ok.
The detect compiler function was changed in 2.8.10 and the assembler support was not modified accordingly.
It seems instead of the _INIT variable the _LIST variable should be set.
I'll post a patch later today.

Can you please put the two attached files in your cmake installation and see whether this makes it work better for you, both in the case that you have yasm in the PATH and that you don't have if it in the PATH ?

Thanks

Now with the new files when yasm is not found CMAKE_ASM_NASM_COMPILER is set to CMAKE_ASM_NASM_COMPILER-NOTFOUND and I see "Didn't find assembler". When found it's set to the full path.

Merged into next, so it should be in the next release.
