Translations:CompileOnWindows - Reducing Disk Footprint/22/en

Open FreeCAD (CMakeLists.txt) with Qt creator, and it will invite you to run cmake. Run it. CMake will build a test program, to see if the compiler works. If the compiler doesn't work, it will show an error telling exactly that, and listing the build output. The build output should help you identify, what's going wrong. Here is a small list of typical errors:
 * Can't open Kernel32.lib - something's wrong with LIB or LIBPATH environment variables (note: they set under kits tab in Qt, not in windows!).
 * Can't resolve external symbol - something's wring with LIB or LIBPATH (they probably point to .lib-s of wrong bit-ness).
 * Manifest-related error - PATH does not point to a location where a resource compiler (rc.exe) of right bit-ness is located.
 * Can't locate include - the include location list should contain path to standard headers (C:\Qt\msvc12rip\VC\include on my machine).
