CMAKE_<LANG>_FLAGS_DEBUG_INIT
-----------------------------

Value used to initialize the :variable:`CMAKE_<LANG>_FLAGS_DEBUG` cache
entry the first time a build tree is configured for language ``<LANG>``.
This variable is meant to be set by a :variable:`toolchain file
<CMAKE_TOOLCHAIN_FILE>`.  CMake may prepend or append content to
the value based on the environment and target platform.

See also :variable:`CMAKE_<LANG>_FLAGS_INIT`.
Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in toolchain files Document these variables. Change our convention for setting these variables from: set(CMAKE_C_FLAGS_INIT "...") to string(APPEND CMAKE_C_FLAGS_INIT " ...") so that any value previously set by a toolchain file will be used. Automate the conversion with: sed -i 's/set (\(CMAKE_\(C\\|CXX\\|Fortran\\|RC\\|ASM\\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \ Modules/Compiler/.cmake Modules/Platform/*.cmake and follow up with some manual fixes (e.g. to cases that already meant to append). Also revert the automated changes to contexts that are not protected from running multiple times. 2016-07-05 13:35:13 -04:00			`CMAKE_<LANG>_FLAGS_DEBUG_INIT`
