Kefu Chai e25c046f31 cmake: pass "CC" using configure when building liburing
since liburing's configure checks the CC and CXX env variables, let's
pass them when calling "configure". otherwise "make" still uses gcc and
g++ by default as they are specified in the "configure" script. this
also matches with the way how debian/rules calls "make".
