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.
