Variables such as CMAKE_COMPILER_IS_GNUCC are documented as obsolete/deprecated and ideally shouldn't be used in the code anymore to have clearer compiler identifications. In the past QCC compiler was identified as GNU and also had this variable set to 1 (see policy CMP0047). Same still applies for LCC compiler (see policy CMP0129).
