There was a problem hiding this comment.
If only -Wall is the problem, could you only turn off -Wall for clang-cl. E.g. leave this if as-is and do:
if (NOT (CMAKE_CXX_COMPILER_ID MATCHES "Clang" AND MSVC))
EnableCompilerFlag("-Wall" true true)
endif ()

Updates CMake build to pass
/clang:-Wallinstead of-Wallwhen clang-cl is used. clang-cl accepts many arguments supported by either MSVC and Clang, but when they conflict, interprets them as MSVC would. In this instance,-Wallwas being mapped to-Weverythingand enabling every available warning.Also adds clang-cl Appveyor build jobs.
