first try to get version from git
fix getting SHA1

TODO : get the short version
fix git version get
link to MaxAPI.lib rather than let the system find the right one (conflict with MaxAPI.framework ?)
avoid failure by discarding return status
better detect Files.h
put everything common to all externals in Shared/Cmake/MaxExternalCommon.cmake
build everything with CMake but j.vimic~
add some other CMakeLists.txt

Warning : this does not work yet !
TODO : add CPM0037 policy where it is needed
add CMakeLists.txt forgotten by git due to annoying global rule

NB : on OS, git installed with brew on 10.9.5 comes with a global ignoring rule (in ~/.gitignore_global )
that ignore file ended with a "~"
no need to detect Carbon ?
add missing CMakeLists.txt to build every externals with CMake system
change all "=" in project name and path to "_equal"

CMake forbid special characters in project name and path
Merge branch 'feature/get-version-from-git' into feature/cmake
