There are various variables like CMAKE_C_FLAGS_<CONFIG> that can influence the
final flags sent to the compiler. Is there a variable that exists or a function
to call to get the final C flags.
What I am trying to do is invoke a custom command to run make on an external
source tree. This makefile has CC, AR, RANLIB CFLAGS and LDFLAGS variables. The
command I would like to do is
add_custom_command(<OUTPUT> COMMAND make CC=${CMAKE_C_COMPILER} AR=${CMAKE_AR}
RANLIB=${CMAKE_RANLIB} CFLAGS=<what to put here> LDFLAGS=<what to put here> ……)
However it doesn’t seem like there is a variable that contains a set of all the
flags that cmake would use. For example, when building on OS X the
-mmacosx-version-min flag gets tacked on by cmake but I can’t find a variable
that contains this flag.
Is there a way to do what I want or am I going to have to manage all the C
flags manually?
