Wow I didn't know about CMAke inserting the project thingy!!!
Ok now let me explain a little more. We want to simplify our
Cmakelists and make macros to help our users.
Now thanks to you we figured out the source of the problem. This is
the CMakeLists we want
SET (CMAKE_USER_MAKE_RULES_OVERRIDE
"${CMAKE_SOURCE_DIR}/CMake/Utils/flag_overrides.cmake") SET
(CMAKE_USER_MAKE_RULES_OVERRIDE_C
"${CMAKE_SOURCE_DIR}/CMake/Utils/c_flag_overrides.cmake") SET
(CMAKE_USER_MAKE_RULES_OVERRIDE_CXX
"${CMAKE_SOURCE_DIR}/CMake/Utils/cxx_flag_overrides.cmake")
PROJECT(rootProject)
# Init our build system INCLUDE (CMake/CMakeInit.cmake)
We want to set the CMAKE_USER_MAKE_RULES_OVERRIDE in the
CMakeInit.cmake so it is hidden to developpers. To do that we must do it
before the PROJECT command or it wont work
But we also want to use CMAKE_SYSTEM_NAME in CMakeInit.cmake which
wont work if we put in CMakeInit.cmake before the PROJECT command.
So we are quite stuck....
You are sort of stuck... It is a chicken and the egg type of problem.
You could try something like this:
project(Foo NONE)
SET (CMAKE_USER_MAKE_RULES_OVERRIDE ...)
enable_language(CXX)
enable_language(C)
Or you could use execute_process in your override files to try and guess
the system yourself.
