Summary:                    ExternalProject_Add: Can't escape ; character in
CMAKE_ARGS
Description: 
Seems ExternalProject_Add became broken from some time ago. I could not figure
out when, but from version 3.5.2 (including 3.5.2-rc1) it does not work anymore.
All ";" characters does replace now by space whenever and not matter how you use
the expression.

Steps to Reproduce: 
ExternalProject_Add(MySubProject SOURCE_DIR ${SUBPROJECT_ROOT}
    CMAKE_ARGS
        -DMYPATH=c:/blabla1;c:/blabla1/blabla2;c:/blabla1/blabla3
    INSTALL_COMMAND "" )

Additional Information: 
I Tried these to workaround it:
1. Quotes around the expression ("-DMYPATH=...")
2. Backlash escaping ("-DMYPATH=...\;...")
3. LIST APPEND instead SET
4. LIST_SEPARATOR in ExternalProject_Add
5. STRING REPLACE ^^ to ;

Nothing works.
