Hi, Attached is a patch that changes the warning of nmake/jom generators when VCVarsAll.bat hasn't been run:
nmake and jom generators no longer warn about missing INCLUDE/LIB environment variables unless the C/CXX compiler cannot be found. This is useful if the user does not want to use these generators with the Visual C++ compiler, or they do not want to enable any language. Sample output; this was run from a clean cmd.exe - i.e. without having run VCVarsAll.bat: C:\Users\JamesJ\AppData\Local\Temp\cmake-warn-build>..\cmake-build\bin\cmake "-GNMake Makefiles JOM" ../cmake-warn -- The C compiler identification is unknown -- The CXX compiler identification is unknown CMake Error at CMakeLists.txt:3 (project): The CMAKE_C_COMPILER: cl is not a full path and was not found in the PATH. To use the JOM generator with Visual C++, cmake must be run from a shell that can use the compiler cl from the command line. This environment is unable to invoke the cl compiler. To fix this problem, run cmake from the Visual Studio Command Prompt (vcvarsall.bat). Tell CMake where to find the compiler by setting either the environment variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.
