build: cleanup CMake (#319)
* build: inline a variable
* build: use `LINKER_LANGUAGE` property for C++ runtime
Rather than explicitly name the C++ runtime, use the `LINKER_LANGUAGE`
property to use the driver to spell the C++ runtime appropriately.
* build: use CMake to control C standard
Rather than use compiler specific flags to control the language
standard, indicate to CMake the desired standard.
* build: use the correct variable
These flags are being applied to the *C* compiler, check the C compiler,
not the C++ compiler.
* build: loosen the compiler check
This loosens the compiler identifier check to enable matching AppleClang
which is the identifier for the Xcode compiler.
* build: hoist shared flags to top-level CMakeLists
This hoists the common shared flags handling to the top-level CMakeLists
from sub-layers. This prevents the duplication of the handling.
* build: remove duplicated flags
This is unnecessary, `/TP` is forced on all MSVC builds, no need to
duplicate the flag for older versions.
* build: loosen C compiler identifier check
Loosen the check to a match rather than equality check, this allows it
to match AppleClang which is the identifier for the Apple vended clang
compiler part of Xcode.
* build: use `add_compile_options`
Use `add_compile_options` rather than modify `CMAKE_C_FLAGS`. The
latter is meant to be only modified by the user, not the package
developer.
* build: hoist sanitizer flags to global state
This moves the CMAKE_C_FLAGS handling to the top-level and uses
`add_compile_options` rather than modifying the user controlled flags.
* build: hoist `-fvisibilty` flags to top-level
These are global settings, hoist them to the top level.
* build: hoist the debug flag handling
Use a generator expression and hoist the flag handling for the debug
build.
* build: hoist the profile flag handling
This is a global flag, hoist it to the top level and use
`add_compile_options` rather than modify the user controlled flags.
* build: remove incorrect variable handling
This seemed to be attempting to set the linker not the linker flags for
the profile configuration. This variable is not used, do not set it.
* build: remove unused CMake includes
