I ran into this problem trying to compile ffmpeg with a QT dependancy.... to get past the not found I had to have a path to windows kit that held the fxc.exe file in my case C:\Program Files (x86)\Windows Kits\8.1\bin\x64. the cause seems to be in my case ? \qtdeclarative-git\plugins\scenegraph\d3....the make file has 26 shader header files it is trying to create with fxc.exe . Adding the path gets rid of the file not found BUT it does not get rid of the compile error the command in the make file does not execute correctly at this point it gives a too many files error . (I am still working on that part of it before I bug report it . This is assuming I am using the right fxc.exe and it can be run correctly from inside the build environment in my case mingwin. So if you have any feedback on how you got this working (IF) it would be appreciated here as well .
I suspect that the make file has a TAB before the command that is causing the problem
because if i cut and paste the commands with the tab i get errors but if i remove the tab it runs fine .
