CMake build instructions do not work for paths with ampersand

[FHof]

When I clone glog into a folder which has an ampersand in its absolute path, the compilation fails:

~/Downloads/before&after_ampersand/glog$ LC_ALL=C cmake --build build
[  4%] Copying find modules...
/bin/sh: 1: after_ampersand/glog/build/share/glog/cmake: not found
make[2]: *** [CMakeFiles/glog.dir/build.make:62: share/glog/cmake/FindUnwind.cmake] Error 127
make[1]: *** [CMakeFiles/Makefile2:1084: CMakeFiles/glog.dir/all] Error 2
make: *** [Makefile:163: all] Error 2

How to reproduce

• Create a folder before&after_ampersand and change the directory to it
• Execute the build steps shown in the Readme: https://github.com/google/glog/tree/c8f8135a5720aee7de8328b42e4c43f8aa2e60aa#building-glog-with-cmake

I think it may be a cmake problem rather than glog.

cmake

It works fine with fancy things like dots, eszett (ß), etc. But there are other characters that lead to fail, namely tabulation, newline and any of "#$:;\| (ASCII 9, 10, 34, 35, 36, 58, 59 ,92, 124). Noticeable it works fine with other non-printable characters, single quotes, etc. in directory name.

It’s better not to not contain the characters in path.

ok, thank you for the information.
