OBJCXX
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.
If OBJCXX
is not defined, the CXX environment variable will be checked instead.
