For cross-compilation with cmake you should use toolchain file, where you specify location of compilers' paths and library search paths. See official documentation of cmake [1]. Also, you can find example of cross-compilation setup for WebKitGTK at [2].

BTW, if you build cross-compiler with buildroot, it generates cmake toolchain files as well.
