[CMake] Assembler handling in 2.8.5 vs 2.8.4

[Florian Reinhard]

Hi,

in 2.8.4 i added these lines to my project and had .asm files compiled
correctly:

...set C/CXX compiler and how they are called...
ENABLE_LANGUAGE(ASM)
SET (CMAKE_ASM_COMPILE_OBJECT "<CMAKE_C_COMPILER> -fr=<OBJECT_DIR>
-eo=.asm.obj <DEFINES> <FLAGS> <SOURCE>")

PROJECT (myproject)
...add soruces, libraries and executables etc...


with 2.8.5 i get this :

==============================================================

Unfortunately assembler support is not covered by the cmake docs
shipped with the installation.

Is there an easy fix (e.g. place the SET calls somewhere else) so
assembler support can still be enabled that easily as before?

Thank you in advance,
Florian
