No, AFAIK. What does work is all other build tools supported by cmake (VS project files, nmake/jom). The command looks good. It is a custom command that runs a tool previously generated by the build (llvm-tblgen.exe). After looking that the ouptput of ninja -v, the problem is that ninja is recompiling some of the source files of llvm-tblgen.exe, which regenerates the llvm-tblgen.exe executable, which in turn triggers the regeneration of the files produced using that tool. Here, the first chunk of output of ninja -v, whith comments: # Ninja starts recompiling some of the source files of llvm-tblgen.exe. This is wrong, because everything is up to date: [1/71] "C:/apps/CMake2.8ninja/bin/cmcldeps.exe" D:\dev\llvm\llvm\utils\TableGen\ DisassemblerEmitter.cpp utils\TableGen\CMakeFiles\llvm-tblgen.dir\DisassemblerEm itter.cpp.obj.d utils\TableGen\CMakeFiles\llvm-tblgen.dir\DisassemblerEmitter.cp p.obj "Note: including file: " C:\ARCHIV~1\MICROS~2.0\VC\bin\cl.exe /nologo /D WIN32 /D_WINDOWS /W3 /Zm1000 /EHsc /GR /MD /O2 /Ob2 /D NDEBUG -Iutils\TableGen -
