Building CMake without git isn't working #352
Description
When trying to build this project via CMake with the repository not being checked out from git (e.g. downloaded as an archive) it won't build due to CMake grabbing version information from git
string(REGEX REPLACE "^([0-9]+)\\..*" "\\1" VERSION_MAJOR "${GitTagVersion}")
string(REGEX REPLACE "^[0-9]+\\.([0-9]+).*" "\\1" VERSION_MINOR "${GitTagVersion}")
string(REGEX REPLACE "^[0-9]+\\.[0-9]+\\.([0-9]+).*" "\\1" VERSION_PATCH "${GitTagVersion}")
It will throw the following error:
CMake Error at CMakeLists.txt:9 (project):
VERSION "HEAD-HASH-NOTFOUND.HEAD-HASH-NOTFOUND.HEAD-HASH-NOTFOUND" format
