This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

Preferred executable for compiling a specific dialect of assembly language files. ASM<DIALECT> can be one of:

  • ASM

  • ASM_NASM (Netwide Assembler)

  • ASM_MASM (Microsoft Assembler)

  • ASM_MARMASM (Microsoft ARM Assembler)

  • ASM-ATT (Assembler AT&T)

Will only be used by CMake on the first configuration to determine ASM<DIALECT> compiler, after which the value for ASM<DIALECT> is stored in the cache as CMAKE_ASM<DIALECT>_COMPILER. For subsequent configuration runs, the environment variable will be ignored in favor of CMAKE_ASM<DIALECT>_COMPILER.


Options that are required to make the compiler work correctly can be included; they can not be changed.

$ export ASM="custom-compiler --arg1 --arg2"
