Example. It's important to know how CMake distinguishes between lists and plain strings. When you write: set(VAR "a b c") you create a string with the value "a b c". But when you write this line without quotes: set(VAR a b c) You create a list of three items instead: "a", "b" and "c". Non-list variables are actually lists too (of a single element).

CMake's string command is the way to go here.. In case you set the value of the variable yourself and don't get it from some third-party source, you might want to use this approach instead:

test reading a file and getting its binary data as hex string ... string(SUBSTRING "People should use Autoconf" 7 10 substringres).

Now I want to have only the substring: E:/LBM_subversion/source. Is it possible to get last string with the help of CMAKE_CURRENT_SOURCE_DIR?

Tried below approach, but getting more than what i wanted. string(REGEX REPLACE ".*mcpu=(.*)\ .*" "\\1" CPU_TYPE "${CC_OPTIONS}").
