In current cmake master, there is this code in
CMakeDetermineASMCompiler.cmake:
...
ELSE("ASM${ASM_DIALECT}" STREQUAL "ASM") # some specific assembler "dialect"
IF(CMAKE_ASM${ASM_DIALECT}_COMPILER_INIT)
SET(CMAKE_ASM${ASM_DIALECT}_COMPILER_LIST
${CMAKE_ASM${ASM_DIALECT}_COMPILER_INIT})
ELSE(CMAKE_ASM${ASM_DIALECT}_COMPILER_INIT)
MESSAGE(FATAL_ERROR "CMAKE_ASM${ASM_DIALECT}_COMPILER_INIT must be
preset !")
ENDIF(CMAKE_ASM${ASM_DIALECT}_COMPILER_INIT)
ENDIF("ASM${ASM_DIALECT}" STREQUAL "ASM")
# Find the compiler.
IF (_CMAKE_USER_CXX_COMPILER_PATH OR _CMAKE_USER_C_COMPILER_PATH)
FIND_PROGRAM(CMAKE_ASM${ASM_DIALECT}_COMPILER
NAMES ${CMAKE_ASM${ASM_DIALECT}_COMPILER_LIST}
PATHS ${_CMAKE_USER_C_COMPILER_PATH}
${_CMAKE_USER_CXX_COMPILER_PATH}
DOC "Assembler" NO_DEFAULT_PATH)
ENDIF (_CMAKE_USER_CXX_COMPILER_PATH OR _CMAKE_USER_C_COMPILER_PATH)
FIND_PROGRAM(CMAKE_ASM${ASM_DIALECT}_COMPILER
NAMES ${CMAKE_ASM${ASM_DIALECT}_COMPILER_LIST}
PATHS ${_CMAKE_TOOLCHAIN_LOCATION} DOC "Assembler")
So, in your case, ${CMAKE_ASM${ASM_DIALECT}_COMPILER_LIST} should be set
to "ml" or "ml64".
This should then go into the second find_program() call, and there it should
be found. The assembler should AFAIK be in the same directory as cl.exe.
Assembler support works currently only in the makefile-based generators.
For having assembler supported in VisualStudio contributions from users are
needed (I don't have Windows, so I can't do that).
