[CMake] CMAKE_INSTALL_PREFIX: Win32 quoting problem

[Mike Jackson]

SET(CMAKE_INSTALL_PREFIX "$ENV{ProgramFiles}\\${PROJECT_NAME}_${VERSION}")

or

SET(CMAKE_INSTALL_PREFIX "$ENV{ProgramFiles}/${PROJECT_NAME}_${VERSION}")

Strings in CMake are like C Strings. '\' is special so it needs to be
escaped with another '\'. You can also use the normal '/' and cmake
_should_ do the right thing with it.
