Fix cmake execute_process working directory (#622)

Browse Source 
Correct the working directory of the execute_process call, to get the version from git tags.
The working directory should be the the directory of this libary. Otherwise, if you include httplib
as a git submodule and call add_subdirectory, the execute_process command will be run in a wrong
directory leading to error.
