ISPCFLAGS

在 3.19 版被加入.

這是一個 CMake 環境變數。其初始值取自呼叫的進程環境。

Add default compilation flags to be used when compiling ISPC files.

CMake uses this environment variable value, in combination with its own builtin default flags for the toolchain, to initialize and store the CMAKE_ISPC_FLAGS cache entry. This occurs the first time a build tree is configured for language ISPC. For any configuration run (including the first), the environment variable will be ignored if the CMAKE_ISPC_FLAGS variable is already defined.

See also CMAKE_ISPC_FLAGS_INIT.
