[CMake] string regexp replace removes the semicolons

[CHEVRIER, Marc]

Hi,

Command file(GLOB) returns a CMake list (in a CMake list, items are separated by ;)

Now you pass to command string the content of the list, so the list is expanded: in your example,
string(REGEX REPLACE "foo.*cc" " " COMPILE_ONLY ${ALL_SOURCES})

Is equivalent to:
string(REGEX REPLACE "foo.*cc" " " COMPILE_ONLY a.cc b.cc foo_u.cc foo_v.cc c.cc y.cc)

So, command string will concatenate all the input strings in a single string.

To keep semi colons, you have to pass ALL_SOURCES as a string, not a list:
string(REGEX REPLACE "foo.*cc" " " COMPILE_ONLY “${ALL_SOURCES}")
