New in version 3.16.7.
This is a CMake Environment Variable. Its initial value is taken from the calling process environment.
Preferred executable for compiling
OBJCXX language files. Will only be used by CMake on the first configuration to determine
OBJCXX compiler, after which the value for
OBJCXX is stored in the cache as CMAKE_OBJCXX_COMPILER. For any configuration run (including the first), the environment variable will be ignored if the CMAKE_OBJCXX_COMPILER variable is defined.
OBJCXX is not defined, the CXX environment variable will be checked instead.
