ASM ------------ .. include:: ENV_VAR.txt Preferred executable for compiling a specific dialect of assembly language files. ``ASM`` can be ``ASM``, ``ASM_NASM`` (Netwide Assembler), ``ASM_MASM`` (Microsoft Assembler) or ``ASM-ATT`` (Assembler AT&T). Will only be used by CMake on the first configuration to determine ``ASM`` compiler, after which the value for ``ASM`` is stored in the cache as :variable:`CMAKE_ASM_COMPILER _COMPILER>`. For subsequent configuration runs, the environment variable will be ignored in favor of :variable:`CMAKE_ASM_COMPILER _COMPILER>`.
