Running CMake on Windows

Question

I am currently trying to get CMake to run on my Windows 7  64-bit  system  I want to compile TagLib for later use with a Qt application I am working on  I would like to compile it with MinGW  not Visual C   as in this other question    I download the installer  cmake-2 8 3-win32-x86 exe  and install it  I also opt to add CMake to my path   I then go to the directory why the CMakeLists txt file is and run cmake    It then gives me this giant error   C  Users Joel Downloads taglib-1 6 3 gt cmake   CMake Warning at CMakeLists txt 1  project     To use the NMake generator  cmake must be run from a shell that can use the   compiler cl from the command line   This environment does not contain   INCLUDE  LIB  or LIBPATH  and these must be set for the cl compiler to   work    -- The C compiler identification is unknown -- The CXX compiler identification is unknown CMake Warning at C  Program Files  x86  CMake 2 8 share cmake-2 8 Modules Platform Windows-cl cmake  28  ENABLE LANGUAGE     To use the NMake generator  cmake must be run from a shell that can use the   compiler cl from the command line   This environment does not contain   INCLUDE  LIB  or LIBPATH  and these must be set for the cl compiler to   work  Call Stack  most recent call first     C  Program Files  x86  CMake 2 8 share cmake-2 8 Modules CMakeCInformation cmake 60  INCLUDE    CMakeLists txt 1  project    CMake Error  your RC compiler   CMAKE RC COMPILER-NOTFOUND  was not found    Please set CMAKE RC COM PILER to a valid compiler path or name  -- Check for CL compiler version -- Check for CL compiler version - failed -- Check if this is a free VC compiler -- Check if this is a free VC compiler - yes -- Using FREE VC TOOLS  NO DEBUG available -- Check for working C compiler  cl CMake Warning at CMakeLists txt 2  PROJECT     To use the NMake generator  cmake must be run from a shell that can use the   compiler cl from the command line   This environment does not contain   INCLUDE  LIB  or LIBPATH  and these must be set for the cl compiler to   work    CMake Warning at C  Program Files  x86  CMake 2 8 share cmake-2 8 Modules Platform Windows-cl cmake  28  ENABLE LANGUAGE     To use the NMake generator  cmake must be run from a shell that can use the   compiler cl from the command line   This environment does not contain   INCLUDE  LIB  or LIBPATH  and these must be set for the cl compiler to   work  Call Stack  most recent call first     C  Program Files  x86  CMake 2 8 share cmake-2 8 Modules CMakeCInformation cmake 60  INCLUDE    CMakeLists txt 2  PROJECT    CMake Error at C  Program Files  x86  CMake 2 8 share cmake-2 8 Modules CMakeRCInformation cmake 22  GET FILENAME COMPONENT     get filename component called with incorrect number of arguments Call Stack  most recent call first     C  Program Files  x86  CMake 2 8 share cmake-2 8 Modules Platform Windows-cl cmake 28  ENABLE LANG UAGE    C  Program Files  x86  CMake 2 8 share cmake-2 8 Modules CMakeCInformation cmake 60  INCLUDE    CMakeLists txt 2  PROJECT    CMake Error  CMAKE RC COMPILER not set  after EnableLanguage CMake Error  your C compiler   cl  was not found    Please set CMAKE C COMPILER to a valid compiler path or name  CMake Error  Internal CMake error  TryCompile configure of cmake failed -- Check for working C compiler  cl -- broken CMake Error at C  Program Files  x86  CMake 2 8 share cmake-2 8 Modules CMakeTestCCompiler cmake 52  MESSAGE     The C compiler  cl  is not able to compile a simple test program     It fails with the following output         CMake will not be able to correctly generate this project  Call Stack  most recent call first     CMakeLists txt 1  project    CMake Error  your C compiler   cl  was not found    Please set CMAKE C COMPILER to a valid compiler path or name  CMake Error  your CXX compiler   cl  was not found    Please set CMAKE CXX COMPILER to a valid compi ler path or name  -- Configuring incomplete  errors occurred   C  Users Joel Downloads taglib-1 6 3 gt    I was kind of surprised that it failed so hard out of the box  considering it advertises itself as a cross-platform make   I tried setting INCLUDE  LIB  and LIBPATH  Windows environment variables  all to my MinGW binaries directory  C  MinGW bin  but it s still giving me the same error  I also tried setting CMAKE C COMPILER and CMAKE CXX COMPILER to the location of g    C  MinGW bin g      Does anyone know what s going on here   SOLUTION   Per tibur s suggestion  I ran the cmake GUI to create the make files  I then went into the directory taglib directory and ran mingw32-make exe to do the actual build

The default generator for Windows seems to be set to NMAKE. Try to use:

cmake -G "MinGW Makefiles"

Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.

There is a vcvars32 bat in your Visual Studio installation directory  You can add call cmd exe at the end of that batch program and launch it  From that shell you can use CMake or cmake-gui and cl exe would be known to CMake
