"directory for the project. This is the directory where the project will be "
"built. It can be the same or a different directory than the source "
"directory. For easy clean up, a separate build directory is recommended. "
"CMake will create the directory if it does not exist.\r\n\r\n3. Once the "
"source and binary directories are selected, it is time to press the "
"Configure button. This will cause CMake to read all of the input files and "
"discover all the variables used by the project. The first time a variable "
"is displayed it will be in Red. Users should inspect red variables making "
"sure the values are correct. For some projects the Configure process can "
"be iterative, so continue to press the Configure button until there are no "
"longer red entries.\r\n\r\n4. Once there are no longer red entries, you "
"should click the OK button. This will write the build files to the build "
