Set it to 1:: to include all cgo related files, .c and .go file with "cgo":: build directive, in the build. Set it to 0 to ignore them.:::: CC: Command line to run to compile C code for GOHOSTARCH.:: Default is "gcc".:::: CC_FOR_TARGET: Command line to run compile C code for GOARCH.:: This is used by cgo.
