Invoking a command line with spaces from a variable in a Bash script [duplicate]

Answer 1

The Bash FAQ to the rescue: The quotes are syntactical (meaning the quotes are not part of the name), so you should get the expected result with this:

if test [.... this is Unix ...]
    target="Unix Makefiles"
else
    target="MSYS Makefiles"
fi
cmake . -G "$target"

PS: eval is evil
