[CMake] CMake chokes on hash (#) in CMAKE_MODULE_PATH

[Marcel Loose]

Hi all,

Accidentally, I found out that CMake chokes when CMAKE_MODULE_PATH
contains a hash (#). This already happens when trying whether the C
compiler works. 

The problem is caused by under-quoting of CMAKE_MODULE_PATH in line 2
of /tmp/loose/cmake/#/build/CMakeFiles/CMakeTmp/CMakeLists.txt (see
below).

Best regards,
Marcel Loose.


$ pwd
/tmp/loose/cmake/#/build

$ cat ../CMakeLists.txt
cmake_minimum_required(VERSION 2.6)
project(Hash)

$ cmake --debug-trycompile -DCMAKE_MODULE_PATH="/tmp/loose/cmake/#" ..
debug trycompile on
