3DS build environment

[Robin]

Please delete the build directory, remake it, and try again, adding -G "Unix Makefiles" to the arguments to cmake.

Many thanks. That worked
However I got an error at creating the .smdh file.

Code:

Scanning dependencies of target mgba.3dsx

[ 98%] Generating mgba.smdh
make[2]: *** [3ds/mgba.smdh] Error 57
make[1]: *** [3ds/CMakeFiles/mgba.3dsx.dir/all] Error 2
make: *** [all] Error 2

I thought smdhtool.exe was missing, but it's there in devkitARM/bin. As a workaround I commented out smdh creation in the cmakelists.txt since I can use the .smdh file from the official download package. Still I need to get this sorted out for .cia file creation.
